When I try to view the WebRTC stream from a gstreamer app on my phone,
I do get inbound STUN messages but the libnice says that the message
integrity check failed and I get 401 unauthorized. Wireshark logs say
"Binding Error Response error-code: 401 (Unauthorized)".

Can you please have a look at this https://pastebin.com/fwmgiKty
