I think I managed to isolate problem. When trying to connect to host via scanning for local games, the game tries to connect directly to MAC address hosting the game, which results in an error.
This can be bypassed by:

1. Press Direct Connection button
2. Enter IP address of host computer
3. Hit Join Server and enjoy

I still leave this issue open as it could be potentially very problematic for less technical players.
