WebRTC Grey Screen

[sacha.morin]

Hello,

I’m trying to access Isaacsim using a browser client.

I start Isaacsim with the ./runheadless.webrtc.sh command in a container. I can access the GUI on the same machine using a browser with localhost.

When trying to stream from another computer on the same network, the stream just hangs on a grey screen.

And I get the following error messages in the browser console.

2024-10-07 15:01:36.926 ERROR [streamclient] Stopping Stream with error 0xC0F22206@@

Thanks for your help!

Hi @sacha.morin ,

Thank your for the post.
Could you please try chrome browser which I’ve confirmed to work in my local setup with Isaac Sim 4.2.0

This issue looks similar to

Hi @ToddT,

Turns out it was a firewall issue. We thought we whitelisted ports properly but things started working after disabling ufw completely (which was safe to do given our setup).

Hi @sacha.morin ,

Good to know it works now. Can we say the issue is resolved?

Thanks,
