A friend and I can’t seem to even access Matchmaking at the moment.
Anyone else experiencing this?
Yeah it’s happening to me too. Entering matchmaking would find a match but then stall and back out.
After quitting the game and re-launching it’s stuck on “Contacting Server. Connecting to transport service.”
Edit: after several minutes I can enter matchmaking again but it continually finds players and then backs out and restarts the search.
Same here
I’m having the same issue too with connecting to transport services and then finding matches, but then backing out last second.
Same Here Me and my friend are trying to laso 
Seem to be working for me again.
I got into a firefight match. It seems to be working again now. There was an issue with contacting servers a minute ago.
Had this issue, it got fixed eventually but after getting onto a match it stopped mid match and got a black screen for all players, we were all discussing it on the text bar. Was weird.
It happens sometimes. No clue why. Don’t get it all the time but think 343i are aware of the issues with the servers.
