 . If the remote server also returns VNC traffic on a web socket (which is a case for http://aerokube.com/selenoid/latest/#_live_browser_screen[Selenoid]) - then you should specify a `ws://` URL without trailing `<session-id>` value:

-    ws://my-selenoid-host.example.com/vnc

 Having this URL Ggr will append session ID and proxy VNC traffic from:
