CloudFlare has a lot of bypass issues with their
cdn-cgi/l/chk_jsvc (JS Challenge) and their
cdn-cgi/l/chk_captcha (Under Attack Mode). So, I decided to make a write-up on their issues and how to potentially solve them if you receive any of the following errors.
- DDoS behind CloudFlare
- DDoS with JS Challenge
- DDoS with UAM (Under Attack Mode)
502 Bad Gateway
I wrote up the fix on github because I had struggles with these errors before, and a lot of people want to know how to fix these or want to know how these work.
