I launch the Infinite flight and it keeps saying my account isnt authorized to play when I get to the menu and press ‘a’. Ive tried restarting my console, signing in and out, and checked for updates on the hub or the flight app itself. I have also received both an email on monday about the flight and an email early this morning about being invited. Is there a fix to this or am I missing something?
The same happens to me now as well even though I was already able to access and play some parts of the game.
The same’s happening to me
Same here I played for a bit then opened destiny for a sec came back and now it just spins then times out with not auth
same, don’t know what to do
Have you tried a hard console reset? This fixed it for me. Hold the power button for 10 seconds.
I had this happen to me as well. Try to exit the game and restart - when I did a restart it loaded my account up without having to sign in the next time.
Same here, wanted to play training but I cant get into the game. A few hours I was authorized and able to play.
Edit: console restart worked.
Did you guys get into the insider stuff on halo waypoint? If they didn’t send you any information you may not be in it or may have missed it possibly?
Its back up it just fixed it self
Yep just happened to me as well now. I was playing it 1 hr ago went for lunch and now cant log back in.
I think 343 shut off Halo’s servers across the board. Figured the flight servers were turned off for the upcoming PVP playtime today. However MCC is off too.
(While typing this the MCC servers came back so idk what’s going on. Gonna try Infinite again)
I did every thing I have the code but it won’t let me in
yeah i have the same problem too on PC and i have the copy paste the @ where you log with your Email because the app doesn’t let me and that’s not a virus in my end 
I have the same problem on PC. I can’t use my account even though I received my invitation to this same account, which I used last flight.
Same with me i played for an hour and not its not letting me back in to play
Also having this issue. Super annoying let me try this joint out already aaaah haha.
Any fixes? Reset ain’t working
Pc player here! The same issue as well, just finished the download, prompted to sign in, and receiving the same error. I have done a reset with no luck 
resolved i had to restart my pc total down time 15 mins
Yea it crashed my series x too as I left a training match. I would of thought the game would be somewhat less buggy now but obviously it’s the same.
