When clicking "Test connection" in Tableau Bridge after entering data source credentials, the following error might occur:

"Incorrect username or password for this data source. Confirm that you have the appropriate permission and re-enter your credentials".

However, subsequent refreshes (either scheduled or Run Now) complete successfully.


  • Tableau Online
  • Tableau Bridge
  • SQL-based data source using Initial SQL or Custom SQL


  1. Click OK on the error message.
  2. Save the connection. 
  3. Refresh the extract.


Tableau Bridge produces a false error during testing when Initial SQL or Custom SQL is used.

Additional Information

When using a MySQL standard connection (no Custom SQL) the "test connection" function works as expected.
