Date de publication: Dec 24, 2025
Description

After upgrading Tableau Server, connections from Tableau Desktop fail with the following error message:


Authentication failed.
Error Code: 84223ADA
Unable to connect to Tableau Server.
SSLHandshakeException
PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target


 

Cause

This is a known issue that has been addressed by Tableau development as of version 2021.4.5.

Résolution

To resolve this issue, upgrade Tableau Desktop to version 2021.4.5 or newer (using the most current maintenance release is always recommended). If upgrading is not feasible at this time, please perform the following two steps below, and then choose one of the below options to work around this issue if needed.
 

  1. If you have External SSL enabled from Tableau Server, configure Tableau Server with a chain certificate.
  2. If you have SSL enabled on a reverse proxy or load balancer in front of Tableau Server, configure that proxy or load balancer to send the full certificate chain instead of just the end certificate.
 

Option 1

Ensure all instances of Tableau Desktop are closed.

On Windows
  1. On the Tableau Desktop computer, open regedit
  2. Navigate to Computer\HKEY_CURRENT_USER\Software\Tableau\Tableau 2021.4\Settings
  3. Create a new DWORD value named WorkgroupUseEmbeddedBrowserServerSignIn
  4. For the value enter 1 (leave the radio button on hexadecimal)
On Mac OS
  1. On the Tableau Desktop computer, open Terminal
  2. Run the command: 
    defaults write com.tableau.tableau-2021.4.plist Settings.WorkgroupUseEmbeddedBrowserServerSignIn "1"

Option 2

On Tableau Server, disable the new server sign in experience that leverages the user’s default browser to authenticate by running these commands: 
tsm configuration set -k wgserver.authentication.desktop_externalbrowser -v false
tsm pending-changes apply

Note: this will trigger a Tableau Server restart.
