2 players can't see or hear each other, but everyone else can see and hear them both?

So, I am having issues with two players in my game. I can see and hear both with no issues. Everyone else can see and hear both with no issues.They can hear and see everyone else. However, they cannot see or hear each other. One has Chrome one has Firefox, but I don't think that's the issue, because everyone else can see and hear them both. We have tried multiple games, with no joy. No adware, no blockers, tried all the audio/video suggestions. Neither are blocking the other, both have tried changing all of their audio and video settings with no change, comp restart, reconnect, and still nothing. Everyone can see and hear them except each other. Couldn't find anything like this in the bug forums. Suggestions? I forgot to mention, that we were playing last night, and neither one had issues seeing or hearing the other. 

No solution but having a similar issue. One of my players has had a similar issue. She logged in and we can see her icon but she can't hear us and we can't hear her. When I put the cursor on her icon, there is no volume control and no whisper icon. Tried all the audio and video suggestions as well and several other players are very tech savvy. No luck with any attempts to rectify.

It has now spread to another player. The avatar no longer has the whisper icon in the top right or the volume control. 

My players can see each other's avatar screens, but then they go black instead of going to video. Meanwhile, everyone else can see and hear both of them. There are 5 people total in the game. Only these two cannot see or hear each other, but can still hear and see the other 3 people in the chat. 

But we were able to solve the problem by leaving and joining again. But this solution did not work for the original player that had the problem.

Here is the error they are getting from the console when trying to connect to each other Exausted retries, cannot connect to player: Sabrae | -KQmi5sSwGiD-2lXDrpS app.js?1482949938:45 Connection ERROR: Sabrae | -KQmi5sSwGiD-2lXDrpS (anonymous) @ app.js?1482949938:45 n.emit @ app.js?1482949938:25 t.oniceconnectionstatechange @ app.js?1482949938:25 app.js?1482949938:45 Error: Negotiation of connection to campaign1638318p6fYG1RB6AUc29rkeU19QKQmi5sSwGiD2lXDrpS failed. at RTCPeerConnection.t.oniceconnectionstatechange [as onicechange] (app.js?1482949938:25) (anonymous) @ app.js?1482949938:45 n.emit @ app.js?1482949938:25 t.oniceconnectionstatechange @ app.js?1482949938:25
