• Enter a remote server Uri
• Connect to this
• Stop the remote server (or disconnect network connection or similar)
• Open VS Code, and open a noteboook

User is now unable to run cells, no errors are displayed, user has absolutely no idea why things dont work
This should unblock users when having trouble, or even those who forget to swtich from remote back to local.

Solution:

• Provide a way to unblock the user (without having to file issues)
• When opening a notebook display a modal error message notifying them that we're unable to connect to the remote jupyter server allowing them to either change the connection or view the logs.
