8 players are matched, it divides them up into red and blue, and then the game just drops before the map starts loading. Then repeat this cycle x10 until you finally get a game.
Anyone else having this problem?
When I have connection problems I do a hard reset and it always fixes it. But I never play in parties either.
It may be due to your NAT, try to open the corresponding ports with HALO MCC or enable the DMZ
