Error rendering macro 'tableau-plugin'

[mwright]

Installed

Schuberg Philis Tableau plugin

We've whitelisted the Tableau server in confluence and vise-versa.  When adding a workbook and view, I get the following error on save. 

Error rendering macro 'tableau-plugin' : com.atlassian.renderer.v2.macro.MacroException: unexpected error: please contact your confluence or tableau server administrator: java.net.MalformedURLException: no protocol: Tableau Server/trusted

 Thoughts?
