Can't connect to H5 severs

Only just bought this game, played it for the first time 2 days ago going through the story missions. Only completed 2/3 missions before I had to come off.

Now when I got to load Halo it says I can’t connect to the multiplayer services. I have done all resets known to man on my Xbox and modem. Even tried resetting the Tv (still nothing).

I just want to play my new game :frowning:

The same at me.

The same at me and, when I want see my supplys I have a error code.

Same here. 343, do something!!!

Same here. REQ system went down for me right before a match, couldn’t use any req’s during the match and now I cannot connect to any of the lobbies for matchmaking.
