Error "Communication with the Tableau Protocol Server process was lost" When Refreshing or Creating Extract

Issue

When you try to create or refresh an extract, the following error might occur:

The connection to the data source might have been lost. Communication with the Tableau Protocol Server process was lost.

Environment

  • Tableau Desktop
  • Microsoft Office Access Database Engine 2007 (Version 12.0.4518.1031)
  • Connection to Excel data source in Tableau Desktop 8.1 and earlier
  • Connection to Excel data source using Legacy Connection in Tableau Desktop 8.2 and later, but earlier than 2019.1 (See note in Additional Information)

Cause

This issue is caused by using an incorrect driver (12.0.4518.1031 Microsoft Access Database Engine 2007 driver).

Additional Information

The issue does not reproduce when an earlier version of the Microsoft Access Database Engine 2007 (12.0.6612.1000) is used or when the Microsoft Access Database Engine 2010 driver is used.
 

Note: Starting in Tableau 2019.1, you can no longer create a new Legacy Excel or Text connection. Existing workbooks created with these legacy connections will continue to work until 2019.2, when all support for legacy connections will be removed. See the Legacy Connection Alternatives document in Tableau Community for alternatives to using the legacy connection.
