Halo Reach On PC Offline Issue

I am unable to join any online games or play with friends due to my account being constantly offline, I have tried everything to fix the issue but have been unable to find anything which helps. Whenever I attempt to join a game it says “contacting servers” and it refuses to load.

I’m also having this same issue, ive had the game for three days now and I’ve been unable to do anything except campaign

Silly question, but what internet service provider are you with, because my friend is having the same issue and I have a feeling it could be something to do with that
