Unable to connect to dedicated server

Games Halo 5: Guardians
1

I have just noticed now that my Arena, Warzone and Co Op features do not work. I get there was a problem with the dedicated server.

I have:
Hard Reset my xbox
Power Cycled my router
Re installed the game
Made sure my Nat is open
Checked any ports that needed forwarding
Spoke with my ISP

343 what the hell is going on yesterday it was fine.

EDIT: I also live in Australia my friend is getting this on his xbox.

It’s on they’re end. I have the same problems too, however I don’t have problems with any other game like this. It seems to only work well at certain times.

So yeah my friend that was having the issue decided to test something. He drove over we set up his xbox at my house and vice versa. It workes fine :s
