Can't Connect to friends

I recently bought the game and was able to play a couple of games with my friends for the first couple days but now I am unable to join any games with my friends when we try to que for any game mode. We start to search and when we get into a lobby it starts to load them into the game but leaves me behind and tells me unable to connect to the lobby. My NAT type is open and I have tried ethernet and port forwarding but nothing works and I am unsure of what to do.

Possible xbox live connection issues
