I’m having a weird problem with all of our sites where Cloudflare is showing a 421 error even though the webserver is responding just fine. I have double-checked with the docs and ran the following command from my remote machine and I see the response that I am expecting. However, when visiting the website directly I get the 521 error, sometimes it will work for a few minutes and then returns the 421 error page
The firewall is set to whitelist all traffic from Cloudflare’s network already.
I am really stuck and out of ideas. Any help is appreciated.
