What action should I take when I see the error "Could not connect to server" when using Test Connection between Server and DB?


  • Tableau Server 2018.2.0
  • Red Hat (RHEL) Linux 7
  • MySQL


Sometimes when using the Test Connection button, you may receive an error "Could not connect to server."

To test the connection try one of the following methods:
  1. Publish a workbook containing the MySQL data source and access the View.
  2. Publish the data source extract and run an extract refresh job.
