User disconnects on LinuxGSM

[Ananais]

Hi Folks,

 

Need some assistance with what I think is some kind of networking issue.

 

Over the weekend I migrated my server (Old PC used for LAN games) from Windows To Debian. Everything appeared to have gone as expected, other than the fact that every 10 minutes, there is some kind of network issue which stops the connected users being re-authenticated, and everyone is kicked.

 

No issues connecting to begin with, or reconnecting after the kicks, only after playing for 10 minutes, and always kicks everyone at the same time.

 

So far I have tried;

Disabling mods and starting a new game to test with.

Disabling LiteNetLib, and enabling SteamNetworking. (Default was having LiteNetLib enabled and SteamNetworking disabled).

Enabling both LiteNetLib and Steam Networking.

Disabling both LiteNetLib and Steam Networking (Could not connect to the server in this case).

 

If LiteNetLib is enabled, the error is as below, before all of the normal player disconnecting.

[S]System.Net.Sockets.SocketException (0x80004005): Network is unreachable

With SteamNetworking enabled, the error shows as;

2022-11-01T16:12:34 1540.375 INF [Steamworks.NET] Authentication callback. ID: 76561197964667833, owner: 0, result: k_EAuthSessionResponseAuthTicketCanceled

2022-11-01T16:12:34 1540.911 INF DynamicMusic: 171 successfully removed from Bloodmoon state cache

 

In both cases the initial authentication on login all shows as successful, the client logs only show the disconnected by server message.

 

I appreciate that this is likely something blocking the re-authentication rather than an issue with the game its self, but so far as I can Debian has no firewall installed by default (I am not experienced in linux), and a couple days worth of searching the internet have left me unsure of what to try next, so hoping someone may have an idea on here!

 

Cheers,
