Описание
When running Tableau Server in a virtual environment where underlying hardware might change dynamically, the data engine might become unresponsive and extract-based workbooks might display the following error:
 
Tableau Data Engine Error: 8: No connection could be made because the target machine actively refused it.

Cause
