Error 522 Connection timed out when proxied | OK when DNS Only

I have been having problems with Cloudflare for a month now. Indeed, when I put my sites in “Proxied”, they don’t work anymore and load for a long time before I get a 522 Timed Out error. Before, it was working fine and I didn’t touch anything in the meantime, so I don’t understand where the problem can come from.

I have already tried to disable the server firewall with no result

Thank you for the help you can give me

PS: I’m french, sorry for my possible language mistakes
