Halo 4 booted from matchmaking

In halo MCC I keep getting booted Halo 4 match making. Right before the match starts, it appears as if all players were booted as there is an x by each player’s name. However, my friend who is also in my party tells me that match went on without me. From the players point of view it looks like I wait the match. This is every time since Saturday night and it’s only on the halo 4 matchmaking in halo mcc. All other matchmaking works with no issues…ie… Halo 2, 3, doubles, swat. I don’t know what to do. It is also de-ranking me each time. How can I fix this. Thanks.
