Host stream and mic cannot be seen on other devices

[joy88-allerite]

I deployed my system in AWS. When I run it, some devices can see and hear the host screen and voice but other devices cannot. What should I do about it?

I deployed this app to test it and had the same issue as @joy88-allerite. only devices on the same network can see eachother.

This is because the public stun server on room.js configuration is no longer operative on that url, so cannot produce valid candidates for remote ips.

As quick fix, i've replaced the configuration with the configuration of the library peer.js obviously better solution is to host your own coturn/eturnal instances.

//iceServers: [{ urls: "stun:stun.stunprotocol.org" }]
const configuration = { 
  iceServers: [
    { urls: "stun:stun.l.google.com:19302" },
    { urls: "turn:0.peerjs.com:3478", username: "peerjs", credential: "peerjsp" }
  ],
  sdpSemantics: "unified-plan"
}
