I start the headless container with the following command:
./runheadless.webrtc.sh --no-window --allow-root --gpus all --rm --network=host nvcr.io/nvidia/isaac-sim:2022.1.0
http://<ip address>:8211/streaming/webrtc-client?server=<ip address>
but the the browser shows a gray screen with nothing like this:
Additional information:
OS version:
Hi. Does streaming works when clicking that red play button?
No. Nothing is displayed just the red button disappears.
Does the native streaming or websocket modes work?
I had the same problem.
I use native headless and connect it from the omniverse streaming client successfully, but websocket and webrtc show a gray screen after pressing the start button.
Hi @tuu4208 , can you share the error logs with some more information?
I have exactly the same problem.
When I run ./runheadless.webrtc.sh on a container, the browser shows the same grey screen as above but it does nothing when I press the play button. This is the same even if I try to access the docker from the same PC (e.g., localhost).
Some further information:
Are there some further WebRTC settings needed specifically for the containers?
In websocket modes.
The final reason is that the webrtc mode communicates using fixed ports and does not provide a way to modify the configuration. These ports were not open in my container environment, which caused this problem.
I think WebRTC method chooses a new port if the default one is taken (e.g., [omni.services.transport.server.http.server] http server was meant to start on 8211 but port is taken, starting on port 8034 instead). All the ports WebRTC chooses should be open since we use the --network=host command while running the containers. Am I wrong?
Did you solve the problem? If yes, how did you do exactly?
My specific problem is that the container port mapping to the outside is random, so hard-coded port mapping to a different port causing the problem. Later, I used a virtual machine to ensure that ports are accurate, which can solve this problem.
Maybe I don’t have the same problem (e.g., the websocket socket is directly mapped outside correctly: I guess should be the same with WebRTC).
@Sheikh_Dawood @rthaker do you have any info regarding this issue?
I have exactly the same problem. Any updates?
Any updates on this topic? @Sheikh_Dawood
When I run the webrtc with the --/app/livestream/logLevel=verboseoption, I get the following errors during startup which I believe to be related to webrtc:

Hi. Does Websocket or Native livestreaming works? Are you able to reproduce the issue with Create or Code?
Websocket works. I do not know about Native streaming as I can only check the streaming via a Mac. Please note that WebRTC works if I stream from the native app; the problem is specific to the Isaac Sim container, which is our main usage.
I am not sure about the Create or Code, as I didn’t find their docker images in your database to test them out.
Apologies for the late reply. Can you share the full Isaac Sim logs when running native and also when running from the container please?
I have attached the two logs you asked for. Thank you in advance!

kit_20230626_093711_native.log (1.4 MB)
@ozhanozen I am not reproduce those error with a container. It works on Safari on a Mac with Isaac Sim running in a container on Ubuntu.
Do you run the native app on the same machine as the one with container?
@Sheikh_Dawood, for me, it works neither from Safari nor Chrome. Also, I tested using other Macs (same host PC), and the results were the same.
Yes, I run the native app on the same machine as the one with the container.
