My xbox was on all last night 4/28 through 4/29 when 343 sent out the notice that they are changing the Multiplayer playlists and ending double XP. Since then I have not been able to connect to any matchmaking. Yes I have signed out and back in. Yes I have hardbooted the xbox. I cannot get anny server activity from Halo:MCC…but also it seems Halo 5 is affected too. I normally have no problema playing Multiplayer and I’ve made no changes to my home network sincr I was playing online last night.
