https://github.com/FlareSolverr/FlareSolverr/wiki/Troubleshooting - is the IP address for FlareSolverr and the request the same, are you using a proxy or VPN, have you disabled IPv6?

Have you disabled IPv6? If not, do.

Are you making the request on the same device as FlareSolverr is running on?

@aymenmerabta5 I have exact same issue with different site. It used to work sometime ago but now it doesn't (I can't tell when this happened). Simplest way to test would be open page in browser and copy request as bash script in dev tools and try to execute in bash.
In my case request which works in browser returns 403 in bash, I also tried to use PowerShell script .... same result. So, somehow CF detects http request outside browser.

See troubleshooting steps above. If you still have issues and are using v3.4.1, provide a debug log of the issue.

I don't think the issue is with flaresolverr, I still have everything working within flaresolverr, but if I extract cookies and execute http request using http client, CF detects it. As I mentioned before extracting request from dev tools should recreate request but it seems something is missing. I use no proxy and I am running flaresoverr locally on windows and same with browser/devtools...

ChatGPT has excellent explanation:

Cloudflare maintains internal models of expected fingerprints for real browsers (Chrome, Edge, Safari, Firefox).
If your TLS fingerprint doesn’t match any of them — for example, looks like “generic curl + OpenSSL” — Cloudflare may:

Serve the JavaScript challenge (/cdn-cgi/challenge-platform),

Delay or deny the request, or

Require solving Turnstile or hCaptcha.
