Halo MCC Multiplayer Not Working

Whenever I try playing any of the Halo games, it connects but when everyone is connected, a little message says “Leaving matchmaking” despite me not pressing any damn buttons. It’s honestly starting to piss me the -Yoink- off. Can someone please help?

This is a known issue right now and 343 are working on a hotfix
