Timed out/Disconnected from my own server

Hi!

I have 3 servers, they are running on another pc in my network. 2 of them works great, but the most populated server, i get disconnected/timed out from every 10-30 seconds. It is really annoying and i can't do a shit.

The console just say that i join, never something about disconnecting.

Anyone have any idea? It shouldnt be something with my network or router because of the other 2 servers work

 

50 slot server - 4gb ram
100 slot = 5.5gb ram
150 slot = 7gb ram
200 slot = 8-9gb ram

 

Right now, middle of the night.
Server 1 - 0 players (2,8gb ram)
Server 2 - 1 players (3,4gb ram)
Server 3 - 4 players (3.4gb ram)

Get kicked from Server 2, but not server 3 or 1. 4,5 gb ram is available.

 

check if their is any type of antivirus blocking the connection, AKA Windows Defender, also check the ports arent the same on some of the servers. Those are the only 2 reasons i can think of.
