Hi, my application would use mediaSoup peer-to-peer. So I don’t have a static IP address. Which is exactly like setting up the demo to work on localhost. How can I configure the demo to use google/twillio’s stun servers? I’m coming from Simple Peer with a configuration like this: [GitHub - feross/simple-peer: 📡 Simple WebRTC video, voice, and data channels](https://github.com/feross/simple-peer#api) ```auto config: { iceServers: [{ urls: 'stun:stun.l.google.com:19302' }, { urls: 'stun:global.stun.twilio.com:3478?transport=udp' }] } ``` I’m getting this message in the client when I try to run both on localhost: `WebRTC: ICE failed, add a STUN server and see about:webrtc for more details` When I look in the about:webrtc, it shows 3 failed candidates with some local IP’s and all the remote IP’s are 0.0.0.0. How do you configure this in development? Thank you! Here’s an interesting thread: [https://groups.google.com/g/discuss-webrtc/c/abtjqfFH3z8](https://groups.google.com/g/discuss-webrtc/c/abtjqfFH3z8) ---

Are you using mediasoup client? If so you just need to add the info to in the client side. recvTransport = mediasoupDevice.createRecvTransport({ iceServers: [.] )} However I do not think you need to use stun and turn servers for local development ---

Hi Rob, I’m trying the [mediasoup-demo](https://github.com/versatica/mediasoup-demo). I can connect webrtc to the hosted version, but when I run the demo servers local on my linux desktop, both my desktop and android can browse to the website but cannot connect webrtc. > **Client console logs** > > ```auto > protoo-client:WARN:WebSocketTransport WebSocket "close" event [wasClean:true, code:1000, reason:""] +0ms mediasoup-demo-app.js:45012:10 > protoo-client:Peer emit "disconnected" +10m mediasoup-demo-app.js:45012:10 > mediasoup-client:Transport close() +10m mediasoup-demo-app.js:45012:10 > awaitqueue stop() +10m mediasoup-demo-app.js:45012:10 > mediasoup-client:Firefox60 close() +10m mediasoup-demo-app.js:45012:10 > mediasoup-client:Producer transportClosed() +10m mediasoup-demo-app.js:45012:10 > mediasoup-client:Producer transportClosed() +1ms mediasoup-demo-app.js:45012:10 > mediasoup-client:Transport close() +3ms mediasoup-demo-app.js:45012:10 > awaitqueue stop() +4ms mediasoup-demo-app.js:45012:10 > mediasoup-client:Firefox60 close() +4ms mediasoup-demo-app.js:45012:10 > protoo-client:WebSocketTransport _runWebSocket() [currentAttempt:1] +10m mediasoup-demo-app.js:45012:10 > GEThttps://192.168.254.23:3000/favicon.ico > [HTTP/1.1 404 Not Found 1ms] > > Download the React DevTools for a better development experience: https://fb.me/react-devtools react-dom.development.js:25001 > mediasoup-demo DOM ready +0ms common.js:120 > mediasoup-demo run() [environment:development] +1ms common.js:120 > mediasoup-demo:RoomClient constructor() [roomId:"os5blo3e", peerId:"1i940cdv", displayName:"Manaphy", device:firefox] +0ms common.js:120 > Warning: componentWillReceiveProps has been renamed, and is not recommended for use.

Mediasoup server is not a STUN/TURN client. It uses an address supplied in the configuration file as its own address when establishing the connection. See webRtcServerOptions .listenInfos.announcedIp in the config.js. You need to change it to an address of some local network interface that the browser is able to connect (not 127.0.0.1 / localhost). If there is no static host address, then, for example, a dynamic one provided to your computer by the DHCP server will do. ---

Hi @snnz , thanks for the reply. I got my ip from [whatismyip.com](http://whatismyip.com), tried this command, verified it was set in config.js, but I’m still getting the same behavior: ```auto MEDIASOUP_ANNOUNCED_IP=111.111.111.111 npm start ``` I was wanting to use mediaSoup in an Electron desktop app, but I don’t think it’s going to work. Do you know anyone who’s gotten that to work? Anyways, cool project and thanks for your help! ---

Providing that the signalling is working properly, you should see this address as a remote candidate in about:webrtc. Try to figure out what the browser tries to pair with it and what is the result. ---

@Michael777 help me better understand what you did. You cloned the demo project, built the react app and run the server. How did you server the web app? Are you able to view the web app? Are you able to run the server. if you try to access the server from the browser over whatever port you used, what do you get? Did you follow the doc here? > **[GitHub - versatica/mediasoup-demo: mediasoup official demo application](https://github.com/versatica/mediasoup-demo)** > > mediasoup official demo application.

I just tried it again with my dev env: Ubuntu (Mint), zsh, nvm, and node 18. I started with the instructions [here](https://github.com/versatica/mediasoup-demo#installation) After I copied the config, I didn’t change it, I just made certs where it expected: ```auto mkdir certs cd certs openssl req -newkey rsa:2048 -nodes -keyout privkey.pem -x509 -out fullchain.pem ``` Then I ran `MEDIASOUP_ANNOUNCED_IP=111.111.111.111 npm start` In another gnome-terminal tab, I started the client app: ```auto cd ../app npm install --legacy-peer-deps npm start ``` It opens my default browser (Firefox latest) and I get a bunch of “connection failed: wss://192.168.254.23:4443/?roomId=ggmr40zs&peerId=st7m39in&consumerReplicas=undefined.” so I opened those with https to clear the cert error. Then I see console messages in both browser and app scroll by as they talk through protoo. Refresh and in Firefox I see `WebRTC: ICE failed, add a STUN server and see about:webrtc for more details`. If I close FF tab and open the same URL in Chrome, I don’t get those messages. Then I try to open the invitation link in Android Chrome, it connects to the web app, but I never get video to/from the desktop. I’ve been using this setup for Webrtc testing w/ SimplePeer, so I know it can work. mediaSoup looked interesting because of its process model and media pipeline. Is there a simpler demo I could start with? I’m not a WebRTC expert, but for my use case (Web App that connects Electron apps peer-to-peer), I’m pretty sure I’ll need at least one side to have a full ICE implementation. Do you see how mediaSoup could work in Electron apps peer-to-peer? Thank you! ---

Where is the server part? Do you have a server run on 192.168.254.23:4443?
