Issue

Cause

FIPS enforcement at the host operating system level will block some of Tableau Server's internal communications required to successfully interact with data source drivers.

Additional Information

Tableau currently isn't developed to operate under an enforced FIPS standard. While some versions of Tableau Server may operate without noticeable issues under FIPS enforcement, performance over time cannot be guaranteed.
