So I have this problem of not being able to play custom games. Whenever I try to join a custom game I get this message:
> CONNECTION FAILED
>
> Your connection to the game session has failed, please try again.
Every time I try to join a custom game I get this message. I can play matchmaking games without problems, but I cannot play custom games which are my favorite part. My NAT is OPEN. So that is not the problem. I have it set so that it automatically updates and when the game first came out I was able to play custom games without problems and only matchmaking was the problem. Now it’s the exact opposite. My NAT is a cone NAT but I don’t think that should matter. I have no idea what the problem is and if anyone does please say what it could possibly be. I desperately want to play custom games with my friends and I can’t so anything that you can provide would be fantastic.
