This has only started to happen recently and it is quite annoying, When I open games my friends have no problem joining when just trying to join me through steam's "join game" button , But for the last couple of days I've been opening AFK shops and no one has been joining, no one. So I was wondering whats wrong and asked a friend to try and join me through the server browser to see if my tavern even shows up there. It did but he could not join the game, afterwards he tried to join me though the "join game" button in steam and he did manage to join my tavern. This has not happened to me before since I have hosted afk shops before and have had great success with them, now I cannot do so and I cannot make mana(well atleast not over 200 mil). I would love for some help on the issue since I do indeed wish to host shops /games.

Edit: Sorry for not adding the [ISSUE] tag I seemed to have skipped the line that told me to put it in the title.
