Hi
I have a strange problem with my server.
Nobody can log in before I do. Other players are stuck at log in screen.
When I am successfully logging in, they can log in too.
It happens usually when the server is offline for a long time and not in a short range like a restart.
Thx in advance

Adding
I have to try re logging at least 4 5 times before I can enter - then the server turns online.
Nobody can enter before I do.

Please I need your help what could be wrong.
