Are matchmaking servers of toribash 5.02 working or are they taken down because of establishment of new mm?
Mine don't seem to be working for a month or 2 now

I guess they should be working, the new matchmaking stuff is currently still being discussed, so they aren't working on it yet.

Maybe an update to a newer version would work.

umm maybe.. i don't really use steam version much coz it causes many problems so i donno if it works on new update

Recent game client builds use the new matchmaking server.
