Unable to receive images using remote streaming

[tt-232]

Dear community,

I’m new to OmniGibson and am currently setting up a remote WebRTC streaming connection between a headless SLURM-based cluster and my local MacBook.

After connecting to the cluster’s network via VPN, I can successfully access the WebRTC streaming URL. However, when running the demo: python -m omnigibson.examples.robots.robot_control_example --quickstart, I do not receive any images on my local machine, only the grey screen. In terminal, there is this error:

2025-02-18 17:59:45 [17,031ms] [Error] [carb.livestream-rtc.plugin] Stream Server: starting the server failed, 0x800B1002 2025-02-18 17:59:45 [17,031ms] [Error] [carb.livestream-rtc.plugin] Could not initialize streaming components 2025-02-18 17:59:45 [17,031ms] [Error] [carb.livestream-rtc.plugin] Couldn't initialize the capture device.

I have tested with and without a headless tag and also changed to native. There are no differences.

Could you please give me some suggestions on how to fix this issue or is it impossible to remote stream on a headless server? Thank you so much in advance! 🙂

I have resolved the issue—it was caused by the ports being occupied.
