so I am creating a mediasoup library for multiparty conference. It is working inside the same network. But for the purpose of testing I did the port forwarding and it is not working.Actually I am getting mediastream for consume but audio and video is not working on HTML page. I also check the mediasoup logs but there are no error.

configuration:
webRtcTransport: {
listenIps: [{ ip: ‘0.0.0.0’, announcedIp: “103.181.238.206” }], // my public IP address
enableUdp: true,
enableTcp: true,
