I’m participating in the WebRTC free preview and experiencing the following error:

DOMException: Failed to set remote offer sdp: Session error code: ERROR\_CONTENT. Session error description: Failed to set remote video description send parameters…

I have my 443 streaming port and port 9443 secured with streamlock. My IP in not public as this server is internal only.
