One reason for VS Code being unable to connect to your server

This scenario showed up yesterday at a client site when I was delivering bespoke consultation on migration from Studio to VS Code.

The site's servers had been configured to use delegated authentication, but the "Delegated" checkbox hadn't been set against the /api/atelier web application, which is what the members of the InterSystems ObjectScript Extension Pack use to make their connections.

As soon as the we application got its checkbox set and the Server Manager refresh button was clicked, namespaces could be enumerated on the server.
