webmail.domain.com and cpanel.doamin.com is not loading

Issue: when I call webmail.domain.com it’s not loading but at the same time domain.com/webmail is not loading

Solution:

In order to get this issue resolved, it needs to enable Proxy subdomains as below :

Go to WHM
WHM >> Main >> Server Configuration >> Tweak Settings >>Proxy subdomains

Enable the option “Proxy subdomains”

That’s all…..!!!
