halo mmc party up problems

Just want to know if anyone else is haveing problems joining games in a party with friends, we have reset connections, hard booted the xbox and restarted the game, nothing seems to be working, we are having problems joining each other to boot… it will let us search and then it will return one or more people to the “find game” screen.
everyone else having these troubles?

I’ve had this issue. No idea how to fix it.
