Multiplayer issues joining game

[Granvaca]

Good day
There are times when i click on a game and I can join, and other times I get a disconnected error. It is odd me and 2 friends purchased the game. If 1 specific friend hosts the other 2 can join, but if either of the other 2 host, the games can not be joined. any idea why some games can be joined, and some can not?

Do you mean campaign? Campaign can join by anybody.If cant join should be some issue on your internet.

Other like custom map some of them require mod.

It was the campaign game yes, but it was odd we have 3 players if player 1 makes the game, players 2 and 3 can join. If 2 or 3 make the game no one can join. Maybe it is some kind of firewall setting
