Hi everyone,
I am getting Error 522 from CloudFlare, I thought it came from my hosting problem but tried to login into web hosting with real IP address and it still worked. I thought it supposed that the problem from CloudFlare. I installed csf firewall and it is safe to add all ips of cloud flare in allow list of csf firewall to fix this error?

The possible errors are listed here : [URLnofo]https://support.cloudflare.com/hc/en-us/articles/200171906-Error-522-Connection-timed-out[/URLnofo]

If you are using a firewall, yes you have to allow all Cloudflare IPs. It's probably this error or a very similar error.

Absolutely. You can whitelist/auto-allow the CloudFlare network along with any modsec vendors in your CSF configuration with no problems.
