Stuck at "Downloading Latest Data" in MM... Help?

Whenever I’ve tried to access Halo TMCC matchmaking, I get “stuck” at the screen where it says “Downloading Latest Data. Downloading the lastest matchmaking data. Please wait”. But it never ends tho. I don’t know how to get it working again. It has been like this for a week or so. And yes, I do have Open NAT.

I have already tried to:

  • Reintall the game
  • Clear the MAC adress thing (I know it’s not the actual MAC Adress)
  • Cleared the cache
  • Even reinstalled the whole xbox

Soooo, what now?
Thnx

Sidenote: And whenever I end/finish a custom game by myself (haven’t tried with others lately) I just get stuck at the end game scoreboard screen too. So I have to exit the game, quit it manually and restart it again to make it work.

Reset your router.
Hard reset your xbox, esp if you have instant-on mode enabled.
connect your xbox to the internet via a wire, not wireless.
uninstall the screen sharing app if you are in the preview program.

Already did all of that too.
