Question Forbid Admin Page Access for hosted Domains

[marcel.hentschel]

Hey Guys,
right now the Ples Admin Page is accesible with every URL:8443 of our hosted Domains.
We would like to forbid that, so that only our Main Admin URL like admin.ourdomain.de:8443 is allowed to access the Admin Page.
I tried to do it with the "Customized Plesk URL", but that doesnt seem to do what I want.

Customizing Plesk URL

You can choose various options to log in to Plesk Obsidian. By default, you can log in to Plesk via the server IP add...

docs.plesk.com

What is the way to do that?

Thanks
Marcel
