Can't even get into match making

When I go from the menu to the arena multiplayer beta section the skater option has a red triangle with an exclamation mark in it, and when I select it, nothing happens. I have reinstalled it, but nothing has happened. I’m not hating on 343, I just want to play the game. If you know what the problem is, please help.

a few people have had this problem they have said they are working on a fix but no more then that, they say to hard reset your xbox but that doesnt work

Ok thanks, do you know where they said that?

go to a thread in halo 5 beta support called update

Having the same issue and hard restarted the box. I just want to play Halo.
