Critical Connection Failure: Isaac Sim 5.0 Container on Ubuntu 22.04 - Clean Logs but No Connection

Hello, I am facing a critical issue where the Isaac Sim 5.0.0 container starts successfully with a completely clean log, but I am unable to connect to the livestream from my browser. I have spent days troubleshooting this and have exhausted all options. **System Details:** * **Laptop:** ASUS Zenbook Pro UX7602 * **OS:** Ubuntu 22.04.5 LTS * **GPU:** NVIDIA GeForce RTX 3060 Laptop GPU (6 GB) * **NVIDIA Driver:** 535.247.01 (This was installed after a full system purge and is confirmed working). **Confirmation of Correct Setup:** * `nvidia-smi` on the host works perfectly. * The diagnostic command `sudo docker run --rm --gpus all ubuntu:22.04 nvidia-smi` ALSO works perfectly, proving the NVIDIA Container Toolkit is functioning correctly. * The final Isaac Sim startup log shows NO [Error] messages. It successfully finds the GPU, initializes Warp, and reports “Streaming server started” and “app ready”. **The Problem:** Despite a perfect startup log, I cannot connect to the server from my browser. I have tried: * Connecting to localhost, 127.0.0.1, and the machine’s direct IP address. * Using different host ports (e.g., 8888). * Using both `–network=host` and `-p` flags in Docker. * Using `xhost +local:` and all X11 forwarding flags. * Running the container with `–privileged`. * Using Incognito mode and disabling the system firewall. The connection errors are always `ERR_CONNECTION_RESET` or `ERR_SOCKET_NOT_CONNECTED`. **Conclusion:** This appears to be a silent failure of the livestreaming component or a deep networking incompatibility specific to my hardware. The system is correctly configured according to all documentation and diagnostic tests. I am completely blocked and need expert assistance. I can provide the full, clean startup log upon request. Thank you.

Currently, direct connection from a browser is not supported for Isaac Sim 5.0’s livestream. You must use the standalone WebRTC Streaming Client app, which is the officially supported viewer. Attempts to connect using a browser will result in connection errors, even if the logs are clean and the streaming server reports as ready.
