How to Solve Cloudflare Challenge in n8n with CapSolver
Ethan Collins
Pattern Recognition Specialist
Cloudflare's bot protection goes far beyond CAPTCHA widgets. The Cloudflare Challenge — the full-page "Verifying your browser…" screen that blocks access to a site entirely — is one of the most aggressive bot defenses on the web. It runs a full JavaScript challenge in a real browser environment, checks behavioral signals, and fingerprints your TLS connection before it ever lets you through.
Standard automation tools fail here. Not because they can't solve the challenge, but because Cloudflare fingerprints the TLS handshake itself — and any non-browser HTTP client gets blocked before the challenge is even served, or re-challenged immediately after, even with a valid cf_clearance cookie.
In this guide, you'll learn how to build a Cloudflare Challenge scraper in n8n that actually works — combining CapSolver to solve the challenge, a local Go TLS server to spoof Chrome's TLS fingerprint, and an n8n workflow to tie it all together.
What you'll build:
- A dual-trigger workflow (schedule + webhook) that bypasses Cloudflare Bot Management
- A lightweight Go server that makes HTTP requests with a real Chrome TLS fingerprint
- A reusable scraper template you can point at any CF-protected site
- Use-case workflows for scraping, account login, and a standalone challenge solver API — all behind Cloudflare Challenge
- Turnstile workflows — a solver API, a scraping template, and an account login flow for sites using Cloudflare Turnstile (no proxy or TLS server needed)
What Is the Cloudflare Challenge?
The Cloudflare Challenge (also called the JS challenge or Bot Management challenge) is a full-page interstitial that Cloudflare injects before a visitor can access a protected site. You've seen it: a black or white screen with "Verifying your browser…" or "Just a moment…" and a loading bar or Cloudflare logo.
Unlike Turnstile — which is a small widget embedded inside a page — the Cloudflare Challenge takes over the entire page. You cannot access any content until it completes.
| Cloudflare Challenge | Cloudflare Turnstile | |
|---|---|---|
| Where it appears | Full-page interstitial — blocks site access entirely | Embedded widget inside a page (e.g., login form) |
| What it looks like | "Verifying your browser…" loading screen | A small checkbox or invisible widget in a form |
| Who adds it | Cloudflare adds it automatically based on security rules | The website owner embeds it in their HTML |
| Solving approach | AntiCloudflareTask — requires a proxy |
AntiTurnstileTaskProxyLess — no proxy needed |
| Cookie returned | cf_clearance (domain-specific, IP-bound) |
Turnstile token (short-lived, used once) |
| Proxy required? | Yes — same IP must be used for solve and fetch | No |
If you see an embedded checkbox or widget inside a form, that's Turnstile — not this challenge. Check the CapSolver guide on identifying challenge types if you're unsure.
Why Standard HTTP Clients Fail
Here's the problem that most guides skip over: Cloudflare checks your TLS fingerprint, not just your cookies.
When a browser connects to a website over HTTPS, it sends a TLS ClientHello that includes details about its supported cipher suites, extensions, and settings. Cloudflare records this fingerprint (called a JA3 or JA4 fingerprint) and compares it to known browser profiles.
Go's net/http, Python's requests, curl, and most HTTP libraries all have distinct TLS fingerprints. Even if CapSolver successfully solves the challenge and returns a valid cf_clearance cookie, Cloudflare will re-challenge or block the request if it detects a non-browser TLS fingerprint on the subsequent fetch.
The fix: a Go server using httpcloak — a library that spoofs a real Chrome TLS stack including:
- JA3 / JA4 fingerprint
- HTTP/2 SETTINGS frames
- ALPN negotiation
- Header ordering and values
This makes the fetch look exactly like a Chrome browser request at the network level.
Prerequisites
| Requirement | Notes |
|---|---|
| n8n self-hosted | Required — the TLS server must run on the same machine as n8n. n8n Cloud is not suitable for this use case. |
| CapSolver account | Sign up here and get your API key |
| Go 1.21+ | Must be installed on the n8n server. Check with go version. |
| Residential or mobile proxy | Datacenter proxies will fail on most Cloudflare-protected sites. See Proxy Requirements below. |
Setting Up CapSolver in n8n
CapSolver is available as an official integration in n8n — no community node installation required.
Step 1: Open the Credentials Page
Go to your n8n instance and navigate to Settings → Credentials.
Step 2: Create the CapSolver Credential
- Click Create credential (top right)
- Search for "CapSolver" and select CapSolver API
- Enter your API Key from the CapSolver Dashboard
- Leave Allowed HTTP Request Domains set to
All - Click Save
You should see a green "Connection tested successfully" banner.
Important: Every CapSolver node in your workflows will reference this credential. You only need to create it once — all your solver workflows will share the same credential.
Step 1 — Build the TLS Server
This Go server receives fetch requests from n8n and executes them using httpcloak's Chrome TLS profile. It's a small, self-contained binary that you run alongside n8n.
Create the source file
Create a directory and save the following as main.go:
bash
mkdir -p ~/tls-server && cd ~/tls-server
go
package main
import (
"context"
"encoding/json"
"fmt"
"io"
"log"
"net/http"
"strings"
"time"
"github.com/sardanioss/httpcloak/client"
)
type FetchRequest struct {

Proxy string `json:"proxy"`
Body string `json:"body"`
}
type FetchResponse struct {
Status int `json:"status"`
Body string `json:"body"`
Headers map[string][]string `json:"headers"`
}
type ErrorResponse struct {
Error string `json:"error"`
}
func writeError(w http.ResponseWriter, status int, msg string) {
w.Header().Set("Content-Type", "application/json")
w.WriteHeader(status)
json.NewEncoder(w).Encode(ErrorResponse{Error: msg})
}
func fetchHandler(w http.ResponseWriter, r *http.Request) {
if r.Method != http.MethodPost {
writeError(w, http.StatusMethodNotAllowed, "only POST allowed")
return
}
var req FetchRequest
if err := json.NewDecoder(r.Body).Decode(&req); err != nil {
writeError(w, http.StatusBadRequest, "invalid JSON: "+err.Error())
return
}
if req.URL == "" {
writeError(w, http.StatusBadRequest, "url is required")
return
}
if req.Method == "" {
req.Method = "GET"
}
ctx, cancel := context.WithTimeout(context.Background(), 60*time.Second)
defer cancel()
c := client.NewClient("chrome-145", client.WithTimeout(60*time.Second))
defer c.Close()
if req.Proxy != "" {
c.SetProxy(req.Proxy)
}
// Extract user-agent separately so httpcloak uses it instead of its preset value.
headers := make(map[string][]string, len(req.Headers))
var userAgent string
for k, v := range req.Headers {
lower := strings.ToLower(k)
if lower == "user-agent" {
userAgent = v
} else {
headers[k] = []string{v}
}
}
var bodyReader io.Reader
if req.Body != "" {
bodyReader = strings.NewReader(req.Body)
}
hcReq := &client.Request{
Method: strings.ToUpper(req.Method),
URL: req.URL,
Headers: headers,
Body: bodyReader,
UserAgent: userAgent,
FetchMode: client.FetchModeNavigate,
}
resp, err := c.Do(ctx, hcReq)
if err != nil {
writeError(w, http.StatusBadGateway, "fetch failed: "+err.Error())
return
}
body, err := resp.Text()
if err != nil {
writeError(w, http.StatusInternalServerError, "read body failed: "+err.Error())
return
}
w.Header().Set("Content-Type", "application/json")
json.NewEncoder(w).Encode(FetchResponse{
Status: resp.StatusCode,
Body: body,
Headers: resp.Headers,
})
}
func main() {
const port = "7878"
mux := http.NewServeMux()
mux.HandleFunc("/fetch", fetchHandler)
mux.HandleFunc("/health", func(w http.ResponseWriter, r *http.Request) {
w.Header().Set("Content-Type", "application/json")
fmt.Fprint(w, `{"status":"ok"}`)
})
log.Printf("TLS server (httpcloak chrome-145) listening on :%s", port)
log.Fatal(http.ListenAndServe(":"+port, mux))
}Initialize and build
bash
go mod init tls-server
go get github.com/sardanioss/httpcloak/client
go build -o main main.goRun the server
bash
./mainVerify it's running (in a new terminal)
bash
curl http://localhost:7878/healthExpected: {"status":"ok"}
Note: The TLS server must run on the same machine as your n8n instance. The n8n workflow calls it at
http://localhost:7878/fetch. If you're using n8n Cloud, you would need a self-hosted setup — this is one reason self-hosted n8n is strongly recommended for Cloudflare Challenge scraping.
Step 2 — Allow n8n to Call Localhost
By default, n8n blocks HTTP Request nodes from calling localhost addresses (SSRF protection). You need to disable this restriction.
Add the N8N_BLOCK_ACCESS_TO_LOCALHOST=false environment variable and restart your n8n instance. How you do this depends on how you run n8n:
If you run n8n directly:
bash
export N8N_BLOCK_ACCESS_TO_LOCALHOST=false
n8n startIf you use Docker:
Add -e N8N_BLOCK_ACCESS_TO_LOCALHOST=false to your docker run command, or add it to the environment section in your docker-compose.yml.
Workflow: Cloudflare Challenge Solver API
This workflow creates a POST endpoint that accepts a Cloudflare-protected URL and proxy, solves the challenge via CapSolver, and returns the raw cf_clearance cookie and userAgent. No TLS server needed — your application handles the fetch.
How It Works
Webhook (POST /solver-cloudflare-challenge) → Cloudflare Challenge (CapSolver)
→ Format Solution → Respond to Webhook4 nodes, webhook-only, no schedule path, no TLS server dependency.
- Webhook — Receives POST requests with
websiteURLandproxy - Cloudflare Challenge — CapSolver solves the challenge using
AntiCloudflareTask - Format Solution — Serializes
cookiesobject to a cookie string, handles errors viacontinueOnFail - Respond to Webhook — Returns
cf_clearance, serialized cookie string, anduserAgent
Node Configuration
1. Webhook Node
| Setting | Value |
|---|---|
| HTTP Method | POST |
| Path | solver-cloudflare-challenge |
| Respond | Response Node |
This creates an endpoint at: https://your-n8n-instance.com/webhook/solver-cloudflare-challenge
2. CapSolver Node (Cloudflare Challenge)
| Parameter | Value | Description |
|---|---|---|
| Operation | Cloudflare Challenge |
Selects AntiCloudflareTask |
| Type | AntiCloudflareTask |
Full-page Cloudflare Challenge |
| Website URL | ={{ $json.body.websiteURL }} |
The Cloudflare-protected URL |
| Proxy | ={{ $json.body.proxy }} |
Residential proxy in host:port:user:pass format |
| Continue On Fail | true |
Returns structured errors instead of crashing |
CapSolver launches a real browser through your proxy, loads the target URL, and solves the Cloudflare challenge. When successful, it returns a solution object containing:
cookies— an object{ cf_clearance: "..." }with the clearance cookieuserAgent— the exact User-Agent string the browser used during the solve
Note: The field is
websiteURL(nottargetURL) — matching the field name used by all other Solver APIs and the CapSolver node itself.
3. Format Solution (Code Node)
This node is needed because AntiCloudflareTask returns cookies as an object ({ cf_clearance: "..." }), not a simple token string like reCAPTCHA or Turnstile. It serializes the cookie, extracts cf_clearance, and returns a structured error if CapSolver failed.
javascript
const input = $input.first().json;
if (input.error || !input.data || !input.data.solution) {
const errorMsg = input.error
? (input.error.message || JSON.stringify(input.error))
: 'No solution returned — site may not be showing a challenge';
return [{ json: { success: false, error: errorMsg } }];
}
const solution = input.data.solution;
const cookies = solution.cookies;
const cfClearance = (cookies && typeof cookies === 'object')
? (cookies.cf_clearance || '') : '';

}Workflow: Using Cloudflare Challenge Solutions
So far, the Solver API above shows how to get a solved cf_clearance cookie and userAgent. But what do you actually do with them?
Unlike reCAPTCHA or Turnstile where you submit a token in a form field, the Cloudflare Challenge returns a cookie (cf_clearance) that must be sent as a header on every subsequent request. The cookie is bound to the proxy IP and User-Agent used during the solve — both must match exactly on the fetch.
Here's the general pattern:
- Solve the Cloudflare Challenge → Get the
cf_clearancecookie anduserAgentfrom CapSolver - Prepare the request → Build headers with the cookie, matching User-Agent, and Chrome-like
sec-ch-uaheaders - Fetch through the TLS server → Send the request via
http://localhost:7878/fetchto match Chrome's TLS fingerprint - Verify the response → Check if the site returned real content (status 200 with HTML) vs. a re-challenge page
- Process the result → Extract the data you need using the HTML node, Edit Fields, or Code node
Key concept: Standard HTTP clients fail here even with a valid
cf_clearancecookie — Cloudflare fingerprints the TLS handshake itself. The Go TLS server (httpcloak) makes the fetch look exactly like Chrome at the network level. Every workflow that fetches a Cloudflare-protected page must go through the TLS server.
Example: Cloudflare Challenge Scraper
Workflow Flow
Schedule path:
Every 6 Hours → Set Target Config [Schedule] → Solve Cloudflare Challenge
→ Prepare TLS Request → Fetch via TLS Server → Extract ResultWebhook path:
Webhook Trigger → Set Target Config [Webhook] → Solve Cloudflare Challenge
→ Prepare TLS Request → Fetch via TLS Server → Extract Result → Respond to WebhookHow It Works
- Set Target Config — Stores
targetURLandproxy(inhost:port:user:passformat). The Schedule path uses hardcoded values; the Webhook path reads them from the POST body. - Solve Cloudflare Challenge — CapSolver node with
onError: "continueRegularOutput"— continues even if the page isn't currently showing a challenge. - Prepare TLS Request — Code node that converts
host:port:user:passproxy tohttp://user:pass@host:portURL format, serializessolution.cookiesto a cookie header string, and builds Chrome-like request headers with the exactuserAgentfrom the solve. - Fetch via TLS Server — HTTP Request to
http://localhost:7878/fetchusingcontentType: "raw"(not"json"— n8n's JSON mode corrupts the body). - Extract Result — Pulls
status,body, andfetchedAtfrom the TLS server response. - Respond to Webhook — Returns the result as JSON (webhook path only).
Why
contentType: "raw"and not"json"? n8n'sjsoncontent type mode expects body parameters as key-value pairs. If you passJSON.stringify($json)as a string, n8n treats the whole string as a single malformed param and sends{"": ""}to the server. Usingrawmode sends the body exactly as the expression evaluates.

}Workflow: Use-Case Examples
The Solver API and scraper example above show the core pattern: solve the challenge, use the solution to fetch through TLS. The following workflows extend this pattern to production-ready use cases — each with dual triggers (schedule + webhook), persistent state tracking, and structured output. Each requires the same prerequisites: a self-hosted n8n instance, the TLS server running on port 7878, a residential proxy, and a CapSolver credential.
| Workflow | Purpose |
|---|---|
Cloudflare Challenge Scraping — Price & Product Details — CapSolver + Schedule + Webhook |
Scrapes price and product name from a CF-protected page every 6 hours, compares against previous values, alerts on changes |
Cloudflare Challenge Account Login — CapSolver + Schedule + Webhook |
Logs into your own account on a CF-protected site by solving the challenge first, then POSTing credentials through the TLS server |
Turnstile — Solver API |
Exposes a webhook that solves Turnstile and returns the token — no proxy or TLS server needed |
Turnstile Scraping — Price & Product Monitor |
Solves Turnstile, fetches a product page with the token, extracts price & name, and alerts on changes |
Turnstile Account Login |
Logs into your own account on a Turnstile-protected site by solving the challenge first, then POSTing credentials with the token — no proxy or TLS server needed |
Example 1: Scraping — Price & Product Details
This workflow scrapes a product page every 6 hours (schedule) or on demand (webhook), extracts the price using the HTML node, and compares it against the previously stored value.
Schedule path:
Every 6 Hours → Set Target Config → Solve CF Challenge → Prepare TLS Request
→ Fetch via TLS Server → Extract Data → Compare Data
→ Data Changed? → Build Alert / No ChangeError handling: If CapSolver fails, the workflow continues without cookies (via
continueOnFail). The TLS server fetch may still succeed if the page isn't currently showing a challenge.
Key behaviors:
- Uses
dataPropertyName: "body"(not"data") because the TLS server returns{ status, body, headers } - HTML node extracts price and product name via CSS selectors (
.product-price,h1) $workflow.staticData.lastPricepersists the previous price across executions- Price comparison detects both drops (severity:
deal) and increases (severity:info) - Proxy format auto-conversion:
host:port:user:pass→http://user:pass@host:portviatoProxyURL()helper

Triggers are set to periodically check the target website or in response to an external webhook.\n2. Configurations for target URL and proxies are applied.\n3. Cloudflare challenges are solved to navigate website protections.\n4. Secure requests are made to fetch data from the target server.\n5. Extracted data is compared to check for changes.\n6. Alerts are built and dispatched or data returned based on detected changes.\n\n### Setup steps\n\n- [ ] Configure the URL and proxy settings in the 'Set Target Config' nodes.\n- [ ] Connect CapSolver credentials for solving Cloudflare challenges.\n- [ ] Ensure webhook URL is configured correctly to receive external requests.\n\n### Customization\n\nTo adjust monitoring frequency, modify the interval in the 'Every 6 Hours' node or the webhook trigger settings.",

}Example 2: Account Login
This workflow automates login to a Cloudflare-protected site. A Set Login Config node centralizes all parameters — [Schedule] for the schedule path and [Webhook] for the on-demand webhook path.
Schedule path:
Every 24 Hours → Set Login Config → Solve CF Challenge
→ Prepare TLS Login Request → Submit Login via TLS Server
→ Login Successful? → Mark Success / Mark FailedError handling: If CapSolver fails, the workflow continues without cookies (via
continueOnFail). The login request will likely fail, which the Login Successful? node catches.
Key behaviors:
- Uses
cf_clearancecookie +userAgentas HTTP headers (no token in form body — unlike reCAPTCHA login which submitsg-recaptcha-response) - Form fields via
URLSearchParams— edit field names (usernameField,passwordField) in Set Login Config to match your site - Login Successful? checks
status < 400ANDsuccessMarkerin response body - Webhook path returns result as JSON via Respond to Webhook

}Example 3: Turnstile — Solver API
This workflow creates a POST endpoint that solves a Cloudflare Turnstile challenge and returns the token. It's the Turnstile equivalent of the Cloudflare Challenge Solver API above — but simpler: no proxy, no TLS server, just 3 nodes.
Flow:
Webhook (POST /solver-turnstile) → Solve Turnstile (CapSolver) → Respond to Webhook- Webhook — Receives POST requests with
websiteURLandwebsiteKey - Solve Turnstile — CapSolver solves the Turnstile challenge using
AntiTurnstileTaskProxyLess - Respond to Webhook — Returns the solution data (including
token)
Key difference from Cloudflare Challenge: Turnstile returns a
tokenstring, not acf_clearancecookie. You send this token as acf-turnstile-responseheader (or form field, depending on the site) on subsequent requests. No proxy is required.

}Example 4: Turnstile Scraping — Price & Product Monitor
This workflow solves Cloudflare Turnstile, fetches a product page with the solved token, extracts price and product name, and compares against the previous value — alerting on changes. It follows the same dual-trigger pattern (schedule + webhook) as the Cloudflare Challenge scraping example above.
Key difference from Cloudflare Challenge scraping: No TLS server, no proxy, no
Prepare TLS Requestcode node. The Turnstile token is sent as acf-turnstile-responseheader directly through n8n's built-in HTTP Request node.
Schedule path:
Every 6 Hours → Set Target Config → Solve Turnstile → Fetch Product Page
→ Extract Data → Compare Data → Data Changed? → Build Alert / No ChangeWebhook path:
Webhook Trigger → Solve Turnstile → Fetch Product Page
→ Extract Data → Compare Data → Data Changed? → Build Alert / No Change
→ Respond to WebhookKey behaviors:
- CapSolver operation is
Cloudflare Turnstile(notCloudflare Challenge) — usesAntiTurnstileTaskProxyLessunder the hood - Token is sent as a
cf-turnstile-responseheader on the fetch request - No proxy format conversion needed — Turnstile solves don't use proxies
- Standard n8n HTTP Request node — no TLS server required since there's no
cf_clearancecookie to fingerprint-match - Same price comparison logic as the Challenge version:
$workflow.staticData.lastPricefor cross-execution persistence - Webhook path reads
websiteURLandwebsiteKeydirectly from the POST body (noSet Target Confignode needed)

}Example 5: Turnstile Account Login
This workflow automates login to a Turnstile-protected site. It follows the same dual-trigger pattern (schedule + webhook) as the Cloudflare Challenge Account Login above — but without the TLS server, proxy, or custom code node.
Key difference from Cloudflare Challenge login: No TLS server, no proxy, no
Prepare TLS Login Requestcode node. The Turnstile token is submitted as acf-turnstile-responseform field directly through n8n's built-in HTTP Request node. Credentials are sent as standardform-urlencodedbody parameters.
Schedule path:
Every 24 Hours → Set Login Config → Solve Turnstile → Submit Login
→ Login OK? → Mark Success / Mark FailedWebhook path:
Webhook Trigger → Solve Turnstile → Submit Login
→ Login OK? → Mark Success / Mark Failed → Respond to WebhookKey behaviors:
- CapSolver operation is
Cloudflare Turnstile(notCloudflare Challenge) — usesAntiTurnstileTaskProxyLess, no proxy required - Token is submitted as a
cf-turnstile-responseform field in the POST body (not a cookie header like CF Challenge) - No custom code node needed — the HTTP Request node handles form-urlencoded submission directly with
email,password, andcf-turnstile-responsefields - Login OK? checks
statusCode < 400ANDsuccessMarkerin response body — same pattern as the CF Challenge login - Schedule path uses hardcoded credentials in Set Login Config; Webhook path reads
usernameValue,passwordValue,usernameField,passwordField,loginActionURL,successMarkerfrom the POST body - Webhook path supports dynamic field names — the
nameparameter of each form field is an expression ($('Webhook Trigger').item.json.body.usernameField || 'email'), so callers can specify their site's field names

}Conclusion
You've built a complete Cloudflare Challenge bypass pipeline in n8n — no browser automation, no Puppeteer, no Playwright. Just three components working together: CapSolver to solve the challenge, a Go TLS server to spoof Chrome's network fingerprint, and an n8n workflow to orchestrate everything.
The key insight is that solving the challenge is only half the problem. Without matching TLS fingerprints on the subsequent fetch, cf_clearance is useless — Cloudflare inspects the handshake, not just the cookie. The httpcloak TLS server handles that layer, making the fetch indistinguishable from a real Chrome browser at the network level.
The repo now gives you actual starting templates for Cloudflare-protected sites:
- Challenge Solver API — expose a webhook that returns raw
cf_clearance+userAgentfor external apps - Scraping — extract price and product data from Cloudflare-protected pages, with change detection
- Account login — log into your own account behind Cloudflare
- Turnstile Solver API — a 3-node webhook that returns a Turnstile token (no proxy, no TLS server)
- Turnstile Scraping — price monitoring with Turnstile-protected pages using n8n's built-in HTTP Request node
- Turnstile Account Login — log into Turnstile-protected sites with form-urlencoded credentials and a solved token
The Solver API is the simplest entry point — 4 nodes, no TLS server needed. The Turnstile workflows are even simpler — no proxy or TLS server required at all, since Turnstile returns a token (not an IP-bound cookie) and doesn't fingerprint TLS. For Cloudflare Challenge workflows that fetch pages directly, CapSolver solves the challenge and the TLS server makes the actual request. Configure the placeholders, keep the workflows inactive until they match your target, then activate.
Tip: These workflows use Schedule + Webhook triggers, but you can swap the trigger node to any n8n trigger — manual, app event, form submission, etc. After fetching data, use n8n's built-in nodes to save results to Google Sheets, databases, cloud storage, or send alerts via Telegram/Slack/Email.

Frequently Asked Questions
What is AntiCloudflareTask, and how is it different from AntiTurnstileTaskProxyLess?
AntiCloudflareTask solves the full-page Cloudflare Bot Management challenge — the "Just a moment…" screen that blocks site access entirely. It requires a proxy because CapSolver must load the actual protected page through a browser. AntiTurnstileTaskProxyLess solves Turnstile widgets embedded inside pages (login forms, signup forms) and does not require a proxy. Different challenges, different task types.
Why can't I just use n8n's built-in HTTP Request node to fetch the page?
n8n's HTTP Request node uses Go's standard net/http library, which has a distinct TLS fingerprint that Cloudflare detects. Even with a valid cf_clearance cookie, Cloudflare will re-challenge any request that doesn't match a known browser TLS profile. The TLS server solves this by using httpcloak to spoof a real Chrome TLS stack.
Why does my datacenter proxy keep failing?
Cloudflare's bot scoring assigns risk scores to IP addresses. Datacenter IPs (from AWS, GCP, VPS providers, etc.) are well-known and get high risk scores. AntiCloudflareTask uses your proxy to load the challenge page, and if Cloudflare detects the IP as a datacenter, it either serves a harder challenge that CapSolver can't solve, or fails the challenge entirely. Residential and mobile IPs have lower risk scores and pass more reliably.
Do Turnstile workflows need the TLS server or a proxy?
No. Turnstile is fundamentally different from the Cloudflare Challenge. Turnstile returns a short-lived token that you submit as a header or form field — it's not tied to a specific IP or TLS fingerprint. CapSolver solves Turnstile using AntiTurnstileTaskProxyLess, which doesn't require a proxy. And since you're sending a token (not an IP-bound cookie), n8n's built-in HTTP Request node works fine — no TLS fingerprint spoofing needed.
Does cf_clearance expire?
Yes. The expiration depends on the site's Cloudflare configuration — it can range from a few minutes to 24 hours. For recurring scraping jobs, the scheduled workflow (every 6 hours) re-solves the challenge regularly. For on-demand scraping, the webhook path solves a fresh challenge on every request.
