Jitsi Meet works fine - the server Plesk Admin Panel works not more

Hi,

I installed jitsi Meet on a vServer. The Plesk admin interface runs on port 8443

https://x-xx-xxx-xxx.kundenadmin.hosteurope.de:8443

and is now no longer available.
How can I change this?

i think the jitsi videobridge use the port 8443? Should i change this? And how?

thank you
