    An unexpected error occurred on the server

      I'm working with an Access database for the first time.  I created this lovely little dashboard and I tried uploading it to the server and I get the following error below.  I have opened tickets to Tableau a week ago and have heard nothing so I was hoping someone here could assist me.


      An unexpected error occurred on the server. If you continue to receive this error please contact your Tableau Server Administrator.


      DataSourceException: The connection to the data source might have been lost.

      My IT department has installed this driver and the only thing I'm not sure of is if they rebooted the box or if it even needs to be rebooted.

          Sorry your support experience has been less than ideal, unfortunately, that does not seem to be uncommon.


          I would definitely try a reboot of the Server.  That has fixed a lot of issues for me in the past.  Sometimes errors like this occur sporadically due to a network disruption or whatever--so, rebooting may resolve it.


          Be sure to report back when you find out more.
