Thank you for your answer, I´ve just tried your suggestion, and it sadly did not work.
My game is installed on a ssd. and my pc should be able to handle the game.
I have forgot to mention in my original post, that the server (comuntity btw.) is unaccesible in the launcher, It is accesible for my friends, but sometimes they have the same problem.
It used to work just fine with connecting directly to it.
Also when i join i try to put on my jacket, that is laying on the floor. My friend sees it as if ai put it on, but i cant see that. I can also hear him talk to me in game before i get kicked again.
