Omniverse Isaac Sim

Running the Isaac SIM Headless Native App on workstation and cannot connect it from another machine using remote streaming client.
It prints the following lines which means that it was successfully loaded:

[6.752s] [ext: omni.isaac.sim.headless.native-4.2.0] startup
[8.992s] app ready
[9.838s] Isaac Sim Headless Native App is loaded.

On remote client I try to connect and gets the following issue:

I couldn’t find an explanation of this error code nor log files within log directory to understand what is the source of this issue.
I can ping the workstation IP address and connect it through SSH.

We haven’t seen any users report this issue. Are you running the client on Windows?
Could you try opening all the ports for streaming client on the workstation?

3

The client is on Windows.
We try to investigate this issue (it might be blocked ports but we cannot just open all due to security requirements).
If there is a log with more information about this issue it could be very helpful.

5

Please try on other machines or open all ports temporarily to test.

I’m having [almost] the same issue [An unknown error occured (0x100)] on:

  • Server/Workstation: Ubuntu 22.04 (RTX 3080 TI)
  • Client/Local PC: Ubuntu 22.04
  • Isaac sim 4.2.0

My Isaac Sim runs inside the Isaac Lab container built as provided in the IsaacLab repo.

Additional Information:

  • I am able to connect to the server via ssh / ping it.
  • I am able to stream “out of the docker” using the streaming client on the server
  • I am able to stream “out of the docker” using the WEBRTC streaming client on the server itself
  • I am not able to stream from any other machine using the WEBRTC streaming client (connection timeout)
  • I opened TCP/UDP ports as reported here
  • Disabling ufw doesn’t change anything. UFW logs don’t show anything being blocked coming from my client.
  • Using port-forwarding via ssh and WEBRTC client, I end up with a grey screen (seems to be another unresolved issue)
