Neither sending nor receiving video about mediasoup-sample-app

Also I was able to run the mediasoup-demo without problem. But this one is not working and this is my config.js file:

module.exports = {
  listenIp: '0.0.0.0',
  listenPort: 3000,
  sslCrt: '/service/certs/fullchain.pem',
  sslKey: '/service/certs/privkey.pem',
  mediasoup: {
    // Worker settings
    worker: {
      rtcMinPort: 10000,
      rtcMaxPort: 10100,
      logLevel: 'warn',
      logTags: [
        'info',
        'ice',
        'dtls',
        'rtp',
        'srtp',
        'rtcp',
        // 'rtx',
        // 'bwe',
        // 'score',
        // 'simulcast',
        // 'svc'
      ],
    },
    // Router settings
    router: {
      mediaCodecs:
        [
          {
            kind: 'audio',
            mimeType: 'audio/opus',
            clockRate: 48000,
            channels: 2
          },
          {
            kind: 'video',
            mimeType: 'video/VP8',
            clockRate: 90000,
            parameters:
              {
                'x-google-start-bitrate': 1000
              }
          },
        ]
    },
    // WebRtcTransport settings
    webRtcTransport: {
      listenIps: [
        {
          ip: '127.0.0.1',
          announcedIp: '192.168.43.225',
        }
      ],
      maxIncomingBitrate: 1500000,
      initialAvailableOutgoingBitrate: 1000000,
    }
  }
};

Except the server is behind NAT or proxy you don't need to set the announcedIp and setting the ip with the server IP would be enough.

I changed the config.js with this:

     listenIps: [
        {
          ip: '192.168.43.225',
          announcedIp: null,
        }
      ],

192.168.43.225 is my local IP and definitely it is not behind a NAT or proxy but now I am getting this error in server console:

Error: port bind failed due to address not available [transport:udp, ip:'192.168.43.225', port:10001, attempt:1/101]

Sorry! My mistake. I forgot to forward the rtc min and max port for docker.

Also it works only when I set listenIps to something like:

      listenIps: [
        {
          ip: '0.0.0.0',
          announcedIp: '192.168.43.225',
        }
      ],

Can you please give some insight about Ip and announcedIp?
I thought announcedIp is where others will receice stream.

Use ip: '0.0.0.0' and announcedIp: HOST_PUBLIC_IP when creating a transport.

I found this in FAQ of mediasoup

[mkhahani]

ip is the network address that server starts listening on it and announcedIp is the IP address that client connects to. When the server has a public IP and the client is direct to it, then setting the announcedIp is unnecessary, although setting both ip and announcedIp with the same public IP works too.

When the server has several IPs then 0.0.0.0 matches all addresses in the IPv4 address space.
