Comment 4 for bug 1831164

Yes, it looks your `base_url` is not set. As a result, the default url would be:

  ws://$wsproxy_host:$wsproxy_port/

which is:

  ws://192.168.0.1:6784

Depending on the location of your browser, it might not be able to access 192.168.0.1:6784 . You would need to configure `base_url` and using an external accessible IP address (instead of 192.168.0.1).
