Hello

I am using Directadmin server

Almalinux os
php fpm 8.2 8.3 7.1 7.2 versions
nodejs
mysql
redis
cpguard
csf
modsecurity.

Suddenly Websites stop working and if i check status all services are up and running and directadmin also accessable but website shows 521 origin server down cloudflare error and no error logs in logs directory.

i check all firewall ports and its fine. i retart services but website wont start working. but when i reboot server its start working for some hours then again it stopped.
 
Hello,

What will happen if you temporary disable firewall on your server? Will the sites become reachable?
