Unable to Connect to SharePoint OneDrive from Tableau Desktop Due to Certificate Validation Error (ERR_CERT_AUTHORITY_INVALID)

Udgivelsesdato: Sep 25, 2025
Beskrivelse

When attempting to connect Tableau Desktop to OneDrive experience the following error during authentication:

"This site can't be reached  
The webpage at https://connectors.tableau.com/cloudfile-ui/8/index.html might be temporarily down or it  
may have moved permanently to a new web address.  

ERR_CERT_AUTHORITY_INVALID"

  • Connection to OneDrive works fine via web browser but fails in Tableau Desktop.

  • The embedded web view used by Tableau Desktop for OAuth authentication cannot validate the SSL certificate for connectors.tableau.com.

  • Logs indicate an OAuth refresh token failure alongside certificate validation issues.

  • The problem typically occurs in corporate environments with strict network security, proxy servers, or SSL inspection tools that intercept and resign SSL certificates.
     

Løsning

Step 1: Verify SSL Certificate Trust

  • Open https://connectors.tableau.com/cloudfile-ui/8/index.html in a browser on the affected machine.

  • If the browser shows no certificate warnings, export the SSL certificate chain from the browser.

  • Import the missing root or intermediate certificates into the Windows certificate store under Local Machine > Trusted Root Certification Authorities.

Step 2: Check for Network SSL Interception

  • Confirm with your network/security team whether SSL interception or proxy SSL scanning is enabled.

  • Obtain the proxy’s root CA certificate and import it into the Local Machine Trusted Root Certification Authorities store on the affected machine.

Step 3: Re-authenticate OneDrive OAuth Tokens in Tableau Desktop

  • Open Tableau Desktop and edit the OneDrive connection (Data > Edit Connection).

  • Complete the OAuth sign-in flow again to refresh OAuth tokens.

  • If necessary, remove and re-add the OneDrive data source in Tableau Desktop.

Step 4: Update Tableau Desktop

  • Upgrade Tableau Desktop to the latest version to benefit from updated embedded browser components and improved authentication flows.

Step 5: Additional Checks

  • Ensure system date, time, and timezone are accurate.

  • Check for custom hosts file entries that might redirect or block connectors.tableau.com.

    The error is due to Tableau Desktop's embedded web view not trusting the SSL certificate chain, which can differ from the full browser trust chain.

  • This KB is applicable especially in corporate environments with SSL inspection or strict network security policies.

  • If the issue persists after importing certificates, network traces (e.g., Wireshark) may be needed to diagnose SSL handshake failures.

  • If Tableau Desktop is behind a proxy, configure proxy settings within Tableau appropriately.
