Yeah, I solved my issues based on suggestions from here: [Audio Video not working in Demo - #7 by reddy](https://mediasoup.discourse.group/t/audio-video-not-working-in-demo/1071/7)

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.
