Hi, Kannan I solved the issue by configuring the ice servers. The snippet looks like this now. const peer = new Peer({ initiator: true, trickle: false, config: { iceServers: [ { urls: "stun:numb.viagenie.ca", username: "sultan1640@gmail.com", credential: "98376683" }, { urls: "turn:numb.viagenie.ca", username: "sultan1640@gmail.com", credential: "98376683" } ] }, stream, });

Hi Kannan, I've hosted the server into Heroku and the client into firebase hosting. Now, If I test on my own network using multiple devices then it's working fine. But on another network, the video becomes black when I test it with a friend. An error shows in the console is like: Uncaught Error: Connection failed. at d.value (index.js:658) at RTCPeerConnection.t._pc.onconnectionstatechange (index.js:116)
