Sorry, the subject drama was in hopes of getting attention …
I keep getting Error 521 and am at the end of my witts on troubleshooting it and believe that the problem lies with cloudflare.
Fresh install of cyberpanel on centos7 on VPS with OVH ip address.
Domain resolves fine to webserver with non CF dns.
Move domain to CF dns and get a Error 521.
- have added CF IPs to CSF allow
- have disabled CSF
- have enabled dev mode on CF
- have paused CF on the site
- no connection records in CF firewall events
- no connections records in CP/CSF
The requests seem to hit the CF network and blackhole.
Move domain off of CF dns and it resolves to webserver fine.
Problem seem to be with CF?
