Starting about 4-5 days ago, I could not load into any activity with other players through matchmaking, it will try to find players for 10-15s, before loading me into the activity solo (or not at all and continue to try to find players if crucible or gambit) Originally, I could not see players in any public areas, but that seemed to change today as I loaded into the tower and was able to see people there. I have tried restarting my router, clearing my xbox cache, and turning matchmaking on and off through my xbox settings, but still not able to matchmake into any cooperative activities. Is this a known issue? Are there any other fixes to this that I have not tried?
