When you try to log in to Tableau Server from the Tableau Mobile app, after you supply the Tableau Server name but before you enter a user name and password, the following error might occur:

 Not authorized Invalid username or password (errorCode=16)



  • Tableau Server 9.0.0 thru 9.0.3
  • Tableau Mobile app
  • Okta or Horizon IdP
  • iOS


Upgrade to Tableau Server 9.0.4 or a later version.



This behavior is a known issue that has been corrected in recent versions.

Additional Information

Upgrading Tableau Server, not just the Mobile App, is necessary to fully resolve this issue.
