Opennos Connection closed

[einfach2]

I have a Problem connecting with my Server.
When it comes to the login screen, i type in name: admin pw: test.
Right after i get send back to the login screen.
The login console says:
[INFO] 14:14:06 -- New client connected. ClientId = 2
[DEBUG] 14:14:06 -- CONNECT admin Connected -- SessionId: 2
[WARN] 14:14:06 -- Connection closed.

I've opened all important Ports and even tried disabling firewall.

Does someone have an idea?

Edit: Solved can be closed

I've needed an older Version of Nostale. I think I installed the 2016 UK Version. But I've got another Emulator that works with the new Nostale
