You may want to contact Tableau Support for this since no one here knows.
I would recommend downgrading Desktop to 9.0.3 so it matches the Server version. I know, I know, "they" say that only the first two version values have to match but that wasn't so for us a few versions back so I always keep them the same or else Desktop the lesser of the two.
Try re-publishing the workbook, making sure you can connect while you are in Desktop. Don't include external files and, obviously, embed credentials.
