Reinstalling the game didn't help. Resetting the Truckersmp settings and using another profile didn't help either. This still happens on EU servers only. Playing on the US Server works with no problem at all.
Tho i noticed that, when I connect to the EU Server that it sometimes Authenticates my connection before putting me offline, then right after that it crashes.
EDIT: So I tried around a little in hope to fix the crashing issue with not much luck. I tried changing from Directx11 to opengl and directx9. For a while it allowed me to play for roughly 30 minutes on Simulation 2 before i got kicked for unreliable connection. Tho since i did this changing to opengl it seems to not crash that often but rather kick for the unrealiable connection reason. My friend told me this could be due to a bad connection to the server, which shouldn't be the case seince I sit on a 50k connection that is mostly stable. But he also asked me if the vpn that is used in the network of my home could be the issue. Could this eventually be caused by the vpn? (the problem on this would be that i can not access the serverroom, therefore i can't get rid of the vpn since it is like a router box connected to the network)
