As the tittle says, I am suddenly no longer able to connect to competitive or coop games in R2. Nothing has changed about my connection or router, and R2 is the only game having this problem. Anyone know what's up? It was working just fine a day ago. I tried scanning through the forum to see if anyone else was complaining about it, but didn't notice any.
Edit: Found the solution:
Apparently my friend turned on the media server finding feature. Turned it off, online connecting works correctly again. No clue why the in the world it owuld make a difference, but does.
