After succeed to make mediasoup-demo works locally, i started a visio-conferency with other peers, but i can only see my video output and not others, how can i resolve this please ?

Am also having an issue with “Chat unavailable”, is there a configuration, i missed ? is there a way to make it work please ?  
This is my config.js :

```auto
/**
 * IMPORTANT (PLEASE READ THIS):
 *
 * This is not the "configuration file" of mediasoup. This is the configuration
 * file of the mediasoup-demo app. mediasoup itself is a server-side library, it
 * does not read any "configuration file". Instead it exposes an API. This demo
 * application just reads settings from this file (once copied to config.js) and
 * calls the mediasoup API with those settings when appropriate.

You can not use `listenIp.ip = "0.0.0.0"`. It must be a specific bindable IP in your host.

BTW are you reading the mediasoup documentation?

I don’t think you have even read the comment above the setting you have changed. And I don’t think you have any issue with the WebRTC layer but with the WebSocket layer of the mediasoup-demo (because you have set a different port in client and server).

Yes, you have ICE connection problems. Check the forum, there are a recent topic about that.

TIP: you need to learn mediasoup and not just the demo project.
