Halo 4 Competitive Matchmaking problem

Hi people.
I want to know if someone has the same problem in the Competitive Halo 4 list.
The Matchmaking starts and finds all the Players.
Then I see that blue and red team is created.
After that the matchmaking restart! Thats impossible to start a single game…I don’t have any filters ON.
Thank you.

It’s a known issue right now and 343 are working on a hotfix
