SO I cannot play Halo 5 Guardians because apparently dedicated servers hate me. Kind of a pain in the rump to keep getting kicked and no be able to play the game. Just ranting but if you have the same issues it should be brought up.
Same
At the time you were posting there was a service alert out for Xbox Live, it was affecting multiple games. It’s still actually up right now, be sure and keep an eye out on the support page for more details
