Lag in game

My brother has been having terrible lag in game for Halo 5 multiplayer. This is the only game he lags in, as his internet is set up for streaming and is good enough to play games and stream. He has reset everything multiple times. Any idea on what is going on?

If you do a multiplayer connection test in settings on your Xbox it should report an MTU problem. There’s definitely an issue with Xbox services right now. I’m having the same issue.

It has been doing it since Midnight launch and isn’t reporting any such problem as of 2 hours ago, yet the lag is still present. It is something server side for 343.
