If I add a 2nd level domain like example.tld the alias www.example.tld will be created automatically and it is ok, I can delete it if I want
If I add 3nd level domain like mysubdomain.example.tld it can be created as a separate domain
However if I try to add www.example.tld it can’t be created separately. Hestia creates example.tld if it does not exists or returns an error if it exists.
So is there any way to create www.example.tld as a separate domain?
