Can't open Halo 5

Games Halo 5: Guardians
1

I got home today and started halo, then a message popped up and said, “Try again in a while. We’re having trouble connecting to Xbox” Anyone else have this? My other games work just fine, but halo won’t start. Does anyone know how to fix it?

Servers are under attack again due to hackers, sadly most of my games can’t be played.

Try a hard reset.

Exactly what I would have recommended, try it.
