I have tried to play MCC matchmaking and after the updates,I still can’t find any games. Nothing works…
I was / possibly still am having the same issue. Sometimes it matches me with enough players and then “restarts search” right before the map vote starts… Pisses me off. I just noticed my NAT was Strict and changed some settings on my router to make NAT Open. So far it has seemed to fix the issue but who knows…
you could try port forwarding or making sure you have a wired connection-much better that way, but it’s a common prob.
I am SO over this…they HAVE to get this fixed for H5…
I have the same problem 
I’ve played MCC on wifi in the starting months and it does kinda messes up the search so wired is wayyy better. I’m not sure if manual port forwarding or dmz option makes a difference. I also restart my router before playing online cuz at times it’s timed out and I get the restart search issue and rebooting router fixes that.
It probably just means alot of the community wasn’t aware of the update and haven’t done it yet, which is why you aren’t getting matchmade with them. I keep getting the xbox multiplayer is blocked and came here and wouldn’t of realized there even was an update…everything should probably be good now.
I’m too… restart searches or end the match because the server ends
