You can find the reason and a solution here: https://forum.vestacp.com/viewtopic.php?t=5408#p66936

Basicly: use a domain name, not the ip, for webmail (domain.tld/webmail) and it will work.

But it’s better to leave it there and just use a domain name for access webmail instead.

Yes, but so far it’s convenient for me.
In the future, of course, so be it.
