We are trying to get sparkler working with our Tableau 9.0 Server using one of the sample views (Superstore/Product) deployed as part of Tableau Server. 

> The same user defined by sparkler, is able to access the view when logging into the Tableau Server directly.

> We are using a multi-site Tableau Server configuration, and our sample report is loaded into the Default site.

> Sparkler seems to be retrieving a token for our designated user.

> We are using a self-signed certificate.

> Sales Force seems to be downloading the javascript file from the Tableau server.

> The main Tableau Server page displays and the following error is visible in the main content area for the page:

The page could not be accessed.

Either it does not exist, or you do not have the necessary ..... (can't see the rest of the error text)
