Preview 'is no longer available' in 'Converting strings to integers'
Here is the message in the new tab:
Workspace Unavailable This is a preview link for a Treehouse Workspace that is not currently active. If you are the workspace owner, you can launch it again via the Treehouse site.
The selection available in the Preview button selection is 'Port 3000', I'm not used to seeing that.
Any tips or fixes?

Close the preview window, close the workspace, re-launch the workspace, and then open the preview from the new workspace.
