My opponent and I have dropped back to a pristine v1.10 install - no mods what-so-ever - and still I'm getting the communication error.
I'm out of ideas to try - can't imagine what is going wrong - could my ISP (comcast) be blocking something? Do I need to set up some WiFi/internet port number? I'm feeling like the basic connection is good because I can see other challenges (see figure below), my opponent accepted my challenge, it seems to saves the game to the server properly (at least as nearly as I can tell) - it just won't end the turn without the connection error -5.
The issue appears to be ONLY related to me (not my opponent) finishing a turn.
