Data refresh failed for an Excel 2013 file connected to a Tabular model published on a SharePoint 2013 site

Hi,

I've created an Excel 2013 workbook that reads a Tabular model. After publishing it, the related data refresh failed. I've tried to change any settings of the Excel Services application but any results. I've tried to change the authentication settings for the Excel Services options of the Tabular connection inside the Excel file. I've investigated into SharePoint ULS but without any results.

Any suggests? Do I need to create a separate ODC file and publish it on SharePoint?

I've post this issue also in the SharePoint 2013 forums: http://social.technet.microsoft.com/Forums/sharepoint/en-US/e7071df4-2303-4305-a3af-fe3d6c8d0a92/data-refresh-failed-for-an-excel-2013-published-file-on-sharepoint-2013?prof=required
