Online Connection Issues.

[littlemissymoo]

I am trying to play the game online with someone on my friends list and everytime we to play the game online it keeps saying that 'can't connect to game' no matter who sends the invite.
We can both connect online to other players but not each other. Been happening weeks now

I had this same problem with someone on my friends list. I could join a party with them but could not connect to a game with them. I had to change the NAT on my router to 'open' in order to play with them. Hope that helps.
