Hi,

Thanks for reaching out! Usually when this happens, it's because you need to open up the WWT app before running these commands. You can do that either by clicking the "AAS WorldWide Telescope" icon in the JupyterLab launcher, or by going to the View → Activate Command Palette menu item and clicking "AAS WorldWide Telescope" there.

We should special-case this timeout error to suggest the above, since right now we're not giving the user any helpful hints.

Even better would be to be able to automatically launch the WWT app if needed, but last time I looked into the JupyterLab infrastructure, I couldn't figure out a way to make that happen.
