Preview Error - Failed to Render

[bbergstrom]

 am trying to preview an Excel template based on a Qlik Sense app and I'm getting the following error:

The object in question is a KPI and I have tried five different KPI objects and all are failing to render.  This is with a new app, connection and report.

We recently discovered (Friday May 3rd) that some customers are experiencing certificate mismatches between the NPrinting server and the Qlik Sense server.

The solution is to re-export your certificates from the Qlik Sense server and re-import them to NPrinting.
