'Leaving Matchmaking'

I continually get ‘leaving matchmaking’ and returned to looking for players in lobby on PC. I’ve closed the program, signed out of my profile and back in, still doing it. Anyone else?

You’re not the only one. The video game refuses to be played online for about 80% of the matches I queue up for.

Yep I’m getting the same thing while trying to queue into Halo 4 Competitive.

I find a bunch of players, we get divided into teams and then after a few seconds it just leaves matchmaking and continues searching.

It’s a known issue right now, feel free to use this thread for the moment for updates:
