Purpose To make a cloudflare v2 challenge pass successfully, Can be use cf_clearance bypassed by cloudflare, However, with the cf_clearance, make sure you use the same IP and UA as when you got it.
Please use interface mode, You must add headless=False. If you use it on linux or docker, use XVFB.
Challenge are not always successful. Please try more and handle exceptions.
Recommended to install using Docker container on Ubuntu server. DockerHub => https://hub.docker.com/r/vvanglro/cf-clearance
docker run -d --restart always --network host --name cf-clearance vvanglro/cf-clearance:latest \
--host 0.0.0.0 --port 8000 --workers 1
curl http://localhost:8000/challenge -H "Content-Type:application/json" -X POST \
-d '{"proxy": {"server": "socks5://localhost:7890"}, "timeout":20, "url": "https://nowsecure.nl"}'
