Problems with scanning Media libraries and connecting to server

[Wolfgang]

Can you initiate a full library scan and once that completes share your full jellyfin logs via pastebin?

Thank you for your answer.

Well at the moment I unfortunately can't scan anything as after the reinstall the server couldn't be reached anymore. The start_log throws the warnings that I mentionned in my posting above. Maybe this has to do with it...

I'll post a screenshot with the error showing in the WebUI. Translated into English it means "Can't cannot to this server at the moment. Try again later"

So, first problem is to get the connection to the server again.
And then I can try to scan for media again.

Thanks again for your help. I really appreciate that
