Invalid auth session

[s w i f t]

Hello, i´m trying to enter to a server but the game crashes. I´ve spoken to the admin and he sais me that the game crashes by invalid auth session. I can´t fix the problem. Anyone knows how to fix it?

I’ve had this problem and I had to have the steam app opened for any server to load.
