I've had a problem for days, I'm trying to play co-op with my friend. I am the server host and I am trying to access, but he always gets me the same error.
I want to emphasize that I have a good computer and a good connection, I also tried to increase the RAM to 8GB to test but it did not work either. I have been trying to delete a server and create it again, but the same thing always happens to me (When I restart steam or exit the game, I already get the error).
Hope someone can help, I love this game and have a great time.
