vague error "Error resolving authority"

[simonLeary42]

Here is my error message:

[Info  - 17:24:48.514] Resolving ssh remote authority 'ssh-remote+<my-host>' (attemp #1)

The fix for me is to add my key to my SSH agent. After adding my key:

[Info  - 17:27:55.265] Resolving ssh remote authority 'ssh-remote+ansible' (attemp #1)

"Error resolving authority" makes me think of DNS. Can someone with context in the source code explain what "error resolving authority" really means?

authority refers to the authority component of the uri the current vscode window is opening
