Resolved Where to set up Panel Login Domain

[ManuelGDot]

So I have a Plesk install with a Login at:
example.v123.mywebhoster.com:8443

Problem is, I cannot get a cert for that Domain.

I want the Login to Plesk here
example.com:8443

example.com is registered in Plesk.

I never had to change that myself before, cause it was always configured that way. So I'm unsure where to look & google didn't output anything of use, probably used the wrong search tearms.

All help is highly appreciated. Just a link to a helpdesk would be sufficient.

EDIT: Right now example.com:8443 redirects to example.v123.mywebhoster.com:8443 <- that is not what I want.

Have you tried to set your domain in
Tools & Settings > Server Settings > Hostname
?
