Hi All, I’m having some issue getting the app to produce. It fails whilst attempting to publish and get connected to the producer. I’m listening to the `connectionstatechange` event on the producer like so: ```auto switch (state) { case 'connecting': console.log('publishing...'); break; case 'connected': console.log('published'); break; case 'failed': console.log('failed'); liveRef.producerTransport.close(); break; default: break; } }; // later, I'm calling the producerTransport saved into a React Ref. liveRef.producerTransport = liveRef.device.createSendTransport(params); producerTransport.on('connectionstatechange', (eventState) => onProducerTransportConnectionStateChange(eventState) ); ``` Perhaps you guys can spot what I’m doing wrong. Thanks for your help, ---

I think we’ll need more information regarding your code workflow and network structure to identify the problem. The code you shared doesn’t have really much to do with this process - you can actually make the whole thing work without using this event at all. Ensure that you followed all the steps detailed here: [mediasoup :: Communication Between Client and Server](https://mediasoup.org/documentation/v3/communication-between-client-and-server/) ---

Absolutely nothing will happen in the Transport and connection level until you create a Producer on it. This is explained in the docs. ---

Thanks @ibc @dimoochka for the quick response. I appreciate it. Please see more details regarding how I lay down the flow ``` // -- For sending media logic // getRouterRtpCapabilities const data = await sendRequest(SocketActionEvents.GET_ROUTER_RTP_CAPABILITIES, {}); await loadDevice(data); // createWebrtctTranspont on the server/router const params = await sendRequest(SocketActionEvents.CREATE_WEBRTC_TRANSPORT, { consuming: false, producing: true }); // Replicate on the client side by creating the createSendTransport liveRef.producerTransport = liveRef.device.createSendTransport(params); console.log('createSendTransport:', liveRef.producerTransport); // --- subscribe to the `connect` & `produce` event -- // ProducerTransportEvents -> {PRODUCE, CONNECTION_STATE_CHANGE, CONNECT} Object.values(ProducerTransportEvents).map(eventType => { liveRef.producerTransport.on(eventType, (eventData, callback, errback) => { switch (eventType) { case ProducerTransportEvents.CONNECT: onProducerTransportConnect(eventData, callback, errback); break; case ProducerTransportEvents.PRODUCE: onProducerTransportProduce(eventData, callback, errback); break; case ProducerTransportEvents.CONNECTION_STATE_CHANGE: onProducerTransportConnectionStateChange(eventData); break; default: console.log('Unable to find action for ' + eventType); } }); }); // For Receiving media // --- get capabilities -- const data = await sendRequest(SocketActionEvents.GET_ROUTER_RTP_CAPABILITIES, {}); await loadDevice(data); } // --- prepare transport --- console.log('--- createConsumerTransport --'); if (!liveRef.consumerTransport) { // const params = await sendRequest(SocketActionEvents.CREATE_CONSUMER_TRANSPORT, // {}); const params = await sendRequest(SocketActionEvents.CREATE_WEBRTC_TRANSPORT, { consuming: true, producing: false }); liveRef.consumerTransport = liveRef.device.createRecvTransport(params); // --- join & start publish -- Object.values(ConsumerTransportEvents).map(eventType => { liveRef.consumerTransport.on(eventType, (eventData, callback, errback) => { switch (eventType) { case ConsumerTransportEvents.CONNECT: onConsumerTransportConnect(eventData, callback, errback); break; case ConsumerTransportEvents.CONNECTION_STATE_CHANGE: onConsumerTransportConnectionStateChange(eventData); break; default: console.log('Unable to find action for ' + eventType); } }); }); consumeCurrentProducers(liveRef.clientId); } } ``` The above is my current setup for both sending & receiving medias. After this, I’m now consuming the transport and passing the producerId, capabilities and codec. I’m equally going through the referred documentation to ensure I haven’t missed an important step. It’s all learning and additional clarity for me. Thanks again guys! ---

Do you have a produce() call on the client side to start off the whole process? You need to initiate this to start off the sendTransport connection. ---

Yes, I’m doing that here. ```auto const useAudio = true; if (useVideo) { const videoTrack = liveRef.localStream.getVideoTracks()[0]; if (videoTrack) { const trackParams = { track: videoTrack }; liveRef.videoProducer = await liveRef.producerTransport.produce(trackParams); } } if (useAudio) { const audioTrack = liveRef.localStream.getAudioTracks()[0]; if (audioTrack) { const trackParams = { track: audioTrack }; liveRef.audioProducer = await liveRef.producerTransport.produce(trackParams); } } ``` ---

Ok cool. So assuming you’ve implemented the produce and connect events in the sendTransport correctly (and call the callbacks) then perhaps it’s a network / firewall issue. Turn on debug logs and also step through your code to make sure it’s all being executed. ---

Just to circle back… I’ve setup some debugging logs to see what’s going into transport.produce. Upon calling `transport.produce({ kind, rtpParameters, appData })`, the resulted object looks like so: ```auto { iceRole: 'controlled', iceParameters: [Object], iceCandidates: [Array], iceState: 'new', // compared to the demo, this should be connected? iceSelectedTuple: undefined, dtlsParameters: [Object], dtlsState: 'new', dtlsRemoteCert: undefined, sctpParameters: undefined, sctpState: undefined } ``` In the documentation, `iceState` :"new"` means No ICE Binding Requests have been received yet. Not sure what the missing part is. When I ran the mediasoup-demo, iceState is connected at this point. ---

You may specify whether you are doing that in client side or server side. > [@bwoodlt](#): > > Upon calling `transport.produce({ kind, rtpParameters, appData })` , the resulted object looks like so: What does it mean “the resulted object”? The documentation clearly explains what “object” it returns. And BTW `transport.produce()` resolves (it’s async) with a `Producer` instance. To be clear: please, don’t try random things. Follow the documentation: [mediasoup :: Communication Between Client and Server](https://mediasoup.org/documentation/v3/communication-between-client-and-server/#producing-media) > [@bwoodlt](#): > > In the documentation, `iceState` :“new”` means No ICE Binding Requests have been received yet.

@ibc thanks for taking time out to respond. > [@ibc](#): > > You may specify whether you are doing that in client side or server side. On the server side. > [@ibc](#): > > What does it mean “the resulted object”? The documentation clearly explains what “object” it returns. And BTW `transport.produce()` resolves (it’s async) with a `Producer` instance. Resulted object meaning, the resolved promise value which is a `Producer` instance like you said. > [@ibc](#): > > To be clear: please, don’t try random things. Follow the documentation: I’m using the referenced documentation and the API documentations. > [@ibc](#): > > Are you completing the required flow in client side as well? Retracing my steps with breakpoint. With a few more hours of debugging, should be able to find which part is missing/failing. I’m running this in a docker container and passing my `webRtcTransportOptions` like so, hopefully that’s not part of the issue. ```auto webRtcTransportOptions: { listenIps: [ { ip: "172.18.0.5", // docker ip address // announcedIp: "192.168.1.104", // private ip }, ], ....additionalOptions, } ``` ---

I haven’t noticed anything overtly wrong with your code so far… Try turning on verbose mediasoup debugging on both the server and the client side - it gives a ton of information and will give you an idea of where your process is stalling. For further detail, try turning on logging on the server worker and using chrome://webrtc-internals. You could also compare logs between the working demo and your project if you’re still at a loss. ---

@bwoodlt Were you able to resolve this? I’m having a similar issue. ---

@iamgroot I’m still fletching it out. However with help from @dimoochka and @ibc I’ve made some progress. I’m now producing. What I changed was the config, ```auto listenIps: [ { ip: process.env.MEDIASOUP_LISTEN_IP || "0.0.0.0", announcedIp: process.env.MEDIASOUP_ANNOUNCE_IP, // this is my public ip. }, ], ``` Also, set logLevel to debug like so in your mediasoup config object so you can get some logs on the mediasoup side: ```auto mediasoup: { ...otherSettings, workerSettings: { logLevel: "debug" } } ``` Try those and let us know. Having said that, I’m still having some trouble getting feed whilst consuming. Video and audio request are being transmitted. Logs below: ```auto | [29/05/2021 20:11:14.109] [INFO] 2021-05-29T20:11:14.109Z fc-live-server:INFO:Room Received a producer::score. id=4900f227-94d1-43fe-8e78-b73788f13c63, score [{"encodingIdx":0,"score":10,"ssrc":3576693883}], kind=audio request | [29/05/2021 20:11:33.379] [INFO] 2021-05-29T20:11:33.379Z fc-live-server:INFO:Room Received a producer::score. id=0b9d4223-c847-4e3f-8682-b0a7e7fba0c1, score=[{"encodingIdx":0,"score":9,"ssrc":3746539812}], kind=video request | [29/05/2021 20:11:34.564] [INFO] 2021-05-29T20:11:34.564Z fc-live-server:INFO:Room Received a producer::score. id=0b9d4223-c847-4e3f-8682-b0a7e7fba0c1, score=[{"encodingIdx":0,"score":10,"ssrc":3746539812}], kind=video request | [29/05/2021 20:12:11.588] [INFO] 2021-05-29T20:12:11.588Z fc-live-server:INFO:Room Received a producer::score. id=0b9d4223-c847-4e3f-8682-b0a7e7fba0c1, score=[{"encodingIdx":0,"score":0,"ssrc":3746539812}], kind=video request | [29/05/2021 20:12:55.795] [INFO] 2021-05-29T20:12:55.795Z fc-live-server:INFO Disconnected SocketIO Ytt1uW9f9KNrbJD6AAAZ from Room=1 userId=425 ...totalNoOfClient=1 ``` ---

In my case…I had set `paused: true` in the server side consumer object. I removed that and everything seemed to work fine.
