I Started angular by command prompt and SignalRtc.exe (in signalrtc-backend-master\bin\Debug\netcoreapp3.1)
chrome and edge asked me to access camera and microphone and I clicked allow.
Text sends but voice and video not.

There is an error in the websoket connection as you could see in last line. You will have to Google that, it may be related to security in your browser
Is hard to tell without a little more context. In order to work you must have ssl on your servers. Also you may have to enable wss communication, it may be a nat error or any other things
Publish on win server 2012 and iis 8 , chrome console :
WebSocket connection to 'ws://5.160.146.56/sockjs-node/182/aa2hoasq/websocket' failed: Error during WebSocket handshake: Unexpected response code: 200

Install that dependency manually, maybe is missing from package.json

If text is working it means connection between peers has been stablished. I'm not sure what your problems could be, there is any log on console.?
text shows twice.
