I’ve never had any issues with Halo 5 matchmaking until the Hammer Storm update. I played my first game of Grifball fine. The 2nd game booted me after about 15 seconds, the third about halfway through the match. It says I was banned due to a poor connection, but my diagnostics on Xbox say everything is fine. 89 Mb/s Up, 12 Down, 0 Packet Loss, and 81 ms ping. Not sure if it’s just problems with the server or what.
