Subject Re: Data provenance screen is always blank with HTTPS.

Is the result that you get an empty table window, or a blank (literally white) screen?

Can you perform the same action with the Developer Tools open and the network tab activated
to see the response from the server, or use curl to perform the same request on the command
line and examine the JSON response? That should indicate if the actual lineage is being returned
or it’s an error message for unauthorized access. 

This could be a permissions issue, or it could be a coaching issue. Try clearing the browser
cache and reloading the UI.
