• All on the same machine...
• Turn on Remote Access
• Open a browser (Edge in this case) instance to connect to server
• Leave this browser tab open and turn off Remote Access on the desktop tools
• Turn on Remote Access again
• Copy the URL
• Open a new tab (leaving the existing tab open) and browse to the server

Result: Hangs. First browser instance will eventually try to reconnect and will hang as well.

In the dev tools console of the browser lots of 404s.

• Hard quit VS Code on the desktop
• In terminal ps aux | grep vscode-cli

Have to kill one or more of these processes to be able to turn on Remote Access again.
