WebRTC Livestream Cannot Connect from External Network (UDP Port Not Listening) #539
Description
Description
Description
I am running Isaac Sim on a remote server and trying to connect to it using the WebRTC livestream client from my local machine. The Isaac Sim application appears to start correctly and reports that the streaming app is loaded, but there's no streaming by the client.
From port inspection, it seems that the UDP port used for WebRTC media streaming is not opened, which might be preventing the livestream connection from being established.
Environment
Isaac Sim Version: 5.1.0
OS: Ubuntu 22.04
GPU: NVIDIA RTX 4090
Driver: 550
Runtime: Docker / remote server environment
Client: Mac (WebRTC livestream client)
Command Used to Start Isaac Sim
I launch Isaac Sim using the following command:
PUBLIC_IP=$(curl -s ifconfig.me) && \
./isaac-sim.streaming.sh \
--/app/livestream/publicEndpointAddress=$PUBLIC_IP \
--/app/livestream/port=49100
The application starts normally and the terminal output shows:
app ready
Isaac Sim Full Streaming App is loaded
No errors are reported during startup.
Actual Behavior
Isaac Sim reports that the streaming app is loaded.
The WebRTC client cannot connect.
Only the TCP signaling port appears to be open.
Port inspection:
netstat -tulpn | grep 49100
Result:
tcp 0 0 0.0.0.0:49100 0.0.0.0:* LISTEN
Checking UDP ports:
netstat -tulpn | grep 47998
No result is returned.
This suggests that the UDP media streaming port is not opened by Isaac Sim.
