Here is my config file:

const os = require('os');

module.exports =
{
	// Listening hostname (just for `gulp live` task).
	domain: process.env.DOMAIN || 'devmedia1.domain.io',
	// Signaling settings (protoo WebSocket server and HTTP API server).
	https:
	{

		// NOTE: Don't change listenPort (client app assumes 4443).
		listenPort: process.env.PROTOO_LISTEN_PORT || 4443,
		// NOTE: Set your own valid certificate files.
		tls:
		{
			cert: process.env.HTTPS_CERT_FULLCHAIN || `${__dirname}/../data/letsencrypt/live/devmedia1.domain.io/fullchain.pem`,

		}
	},

The listening port and the tls certificates seem to be fine, since I could access the app via https and join a room. The problem is that remote video/audio streams don’t show up. Any idea why?

I’m also wondering where to put the turn server urls?

Thanks in advance.

Make sure this is set up with the server public ip. U can search the forum for similar posts.

Yeah, I solved my issues based on suggestions from here: Audio Video not working in Demo - #7 by reddy

Things to keep in mind:

  • announcedIp should be server’s public ip
  • TLS certificates should be valid

I have put my turn server array in the app/lib/RoomClient.js file, not sure whether that helped or was correct.
