Issue Hostname and subscription with same domain name - SSL issues

[Andrea Bampi]

Server operating system version

Ubuntu 22.04

Plesk version and microupdate number

18.0.73 #3

Hello,
I recently activated 3 different servers, all with U22.04 and Plesk 18.0.73.
I have several other servers with older Plesk versions and I'm used to create as first subscription a "welcome page site" with the same domain name as the hostname.
For example, server28.xxxxx.it
I have no issues accessing Plesk via https using https://server28.xxxxx.it:8443 but I can't find a way to make any SSL certificate work on the welcome page (without :8443).
The default behavior of the server is redirecting to the Plesk login page ignoring the subscription (clearlyu something new with this version of Plesk, never worked like that before); when I disable the access to the Panel changing "Customize Plesk Url" setting, I can finally see the welcome page but it works only in http; https gives security error and the installed certificate (checking in the browser) seems to be the default self-signed Plesk certificate.
Note: I installed a Let's Encrypt SSL in the subscription, no errors.
I'm assuming it's no longer allowed to have a subscription domain identical to the server Plesk hostname? Or it's a bug with a working solution?
thanks

So you have server28.domain.tld as a subscription? If so then it makes sense why it would redirect to the plesk default page instead of the plesk login page without the 8443. The proper way is to leave that subdomain out, edit the customize plesk url to be the server28.domain.tld, then go to tools & settings > ssl/tls certificates and enable the "keep plesk secured" which should go through the process of securing it (you might need to clear on the little slider button to set the address and email if it doesn't go through automatically) and there ya go it's set up (if it already works under server28.domain.tld under 8443 with no ssl errors then that last part isn't needed).
