I have 2 friends of mine who lives in the same apartment (roomates) and we play some Halo MCC together from time to time, but now recently they have started to get kicked out (one of them) almost every time when we matchmake in Halo MCC. They don’t have the best internet line and only have a IPv4 connection (no IPv6) and I’m suspecting that can be the issue because of issues with Teredo, but I’m not sure tho. What do you folks suspect? they can play other games together like COD: Cold War etc. They’re just having issues with Halo MCC.
