Summary

The Chrome extension cannot establish a connection with the OpenClaw relay service running inside a Docker container, despite port 18792 being correctly mapped to the host.

Steps to reproduce

1. Deploy OpenClaw using Docker (OrbStack) on macOS with port mapping 18792:18792.
2. Install the OpenClaw Chrome extension on the host machine.
3. Attempt to connect the extension to http://localhost:18792.

Expected behavior

The Chrome extension should successfully connect to the relay service and communicate with the agent.

Actual behavior

The extension fails to connect, and the relay remains unreachable from the host browser.
