Keeps saying halo host disconnects.

Basically I hop in a lobby of halo 4, host disconnects and then I’m booted to a loading screen. Sometimes it takes 10 minutes, sometimes it won’t load to menu at all. I have attempted to play in over 10 Halo 4 matches now and have yet to complete a single one because of this issue.

same things is happening to me, no idea how to fix it.
