We can see each others games, but I have no idea what isn't working right.
It's pretty possible that you have a firewall enabled. That's pretty common issue while playing multiplayer games. You should disable it, or add exception to the white list. Also, it's possible that you don't have a public IP address, or you have but you have a router, in this case you should also setup port forwarding.
New version of MatchMaker can detect this issue. I will release new version withing a few days, it will add a lot of new features, so until then, try to change the firewall settings, if it helps.
