Just a hunch but are you using multiple data sources? If you try switching the primary and secondary does the issue still occur?
If so, contact support as this could be a bug.
Tableau support provided a response. The source for rendering displays is dependent on the complexity of the image. When I reuest for maps to be displayed on multiple rows, the rendering becomes more complex and the client browser requests the rendering from the server. in doing so, our server must have a certificate handshake which is currently not in place. We need to resolve this issue in our enterprise environment.
Thanks for taking the time to respond to my needs!
