You are receiving black videos? You must be missing listenIps setting, you need to set listenIps.ip to your local ip and announcedIp to 0.0.0.0 on local machine. Not sure about the chat you can search the error inside project. This is demo project, use it as guidance and create your own app. ---

And the video/audio working? If noy kindly show peer connection details from chrome://webrtc-internals. Chat not working is not an issue, you will have to look into the code to find out the cause. ---

I have solved this problem now,you should change the ip ‘0.0.0.0’ to ‘yourIP’ for webRtcServerOptions、webRtcTransportOptions and plainTransportOptions at the end of config.js. Follow is the section you should change. webRtcServerOptions : { listenInfos : [ { protocol : ‘udp’, ip : process.env.MEDIASOUP\_LISTEN\_IP || ‘0.0.0.0’, announcedIp : process.env.MEDIASOUP\_ANNOUNCED\_IP, port : 44444 }, { protocol : ‘tcp’, ip : process.env.MEDIASOUP\_LISTEN\_IP || ‘0.0.0.0’, announcedIp : process.env.MEDIASOUP\_ANNOUNCED\_IP, port : 44444 } ], }, // mediasoup WebRtcTransport options for WebRTC endpoints (mediasoup-client, // libmediasoupclient). // See [mediasoup :: API](https://mediasoup.org/documentation/v3/mediasoup/api/#WebRtcTransportOptions) webRtcTransportOptions : { // listenIps is not needed since webRtcServer is used. // However passing MEDIASOUP\_USE\_WEBRTC\_SERVER=false will change it. listenIps : [ { ip : process.env.MEDIASOUP\_LISTEN\_IP || ‘0.0.0.0’, announcedIp : process.env.MEDIASOUP\_ANNOUNCED\_IP } ], initialAvailableOutgoingBitrate : 1000000, minimumAvailableOutgoingBitrate : 600000, maxSctpMessageSize : 262144, // Additional options that are not part of WebRtcTransportOptions. maxIncomingBitrate : 1500000 }, // mediasoup PlainTransport options for legacy RTP endpoints (FFmpeg, // GStreamer). // See [mediasoup :: API](https://mediasoup.org/documentation/v3/mediasoup/api/#PlainTransportOptions) plainTransportOptions : { listenIp : { ip : process.env.MEDIASOUP\_LISTEN\_IP || ‘0.0.0.0’, announcedIp : process.env.MEDIASOUP\_ANNOUNCED\_IP }, maxSctpMessageSize : 262144 } ---

Came across the same problem. The reason was finally found, because the udp port was not “released” in the security group of the cloud server. You can also try adding “&forceTcp=true” to the url as follows. If it works, the reason for the problem you mentioned is that the udp port is not “released”. ```auto https://x.x.x.x:3000/?info=true&roomId=xxx&forceTcp=true ```
