Cannot connect to Halo5 Guardian servers

Hi,

The last few days I been repeatedly getting errors connecting to the Halo 5 Guardian severs. I have been able to connect without issue a limited number of times.

Is there a major issue going on with the servers or is it demand? Either way please remedy the situation swiftly, it’s genuinely ruining the game experience to where I may have to switch to a stable title!

I have a Xbox One Elite if this makes a difference?
