Thank you again. But still no progress. If I login, I see the following SQL's executed and not more:

[Login Server] Client disconnected from the server, removing client.

So the server is never asked for the Server-List but the database connection clearly works.


Edit:
I found an old backup from 04.2016, replaced the binaries and the Server shows up. Because of incompatible databases, it stops after that. For me it looks like a code issue and I can't work it out (I'm not a coder).
