Server SSl Certificate Doesn't Automatically Renew

I'm having a problem with one of my CWP servers.

It seems that everytime the ssl certificate of the server expires, it doesn't get renewed automatically or it doesn't get renewed at all.

When this happens all the websites hosted in the server go down until the ssl certificate of the server gets renewed.

The only way to make the server work again is to ssh the server as root and run /scripts/generate_hostname_ssl

I have tried changing the name of the server in Server Settings -> Change Hostname but then after 3 months the server goes down again until I run /scripts/generate_hostname_ssl

I have a Pro server and have contacted support a few months ago. They said: "We have activated the Auto-Renew option for Hostname and other SSL Certificates on server."

That didn't fix the problem and it happened again!

I appreciate any help I could get in solving this problem.

Thanks in advance.
