Hello,
My cloudflare works ok, except when I try to visit my website with “https://*…”
Http loads normaly but https throws 521 error immidiately. I have whitelisted all the ports and still nothing…
I’m running a CentOS server with CWP7

Do you have SSL installed on your webserver? You need one for secure communication between your server and CF.
