After your Tableau Server administrator installs a new SSL certificate on the server, you might get one of the following errors when you try to sign in to the server from Tableau Desktop, for example, to publish a workbook: 

Internet communication error: The certificate authority is invalid or incorrect 
Invalid certificate error


  • Tableau Desktop
  • Tableau Server
  • Windows Operating System


In some cases, installing the certificate through a browser does not install the certificate at the operating system (OS) level, so Tableau Desktop still can't publish to Tableau Server. Your administrator must install the certificate manually at the OS level using the steps below.
  1. Sign in to Windows using your administrator credentials.
  2. Click the Start button, and select All Programs > Accessories > Run.
  3. In the Run dialog box, type mmc and click OK.
  4. In the console window, select File > Add/Remove Snap-in.
  5. In the Add or Remove Snap-ins dialog box, under Available snap-ins, select Certificates and then click the Add button.
  6. Select the radio button next to Computer account, and click Next.
  7. Leave on Local computer, and click Finish.
  8. Back in the Add or Remove Snap-ins dialog box, click OK.
  9. In the left pane of the console window, expand Certificates (Local Computer) > Trusted Root Certification Authorities.
  10. Right-click Certificates and select All Tasks > Import.
  11. In the Certificate Import Wizard, click Next, and then click the Browse button to navigate to the certificate (.crt) file used by Tableau Server. Then click Open.
  12. Click Next, verify that Certificate Store = Trusted Root Certification Authorities, and click Next.
  13. Click Finish. Click OK to dismiss any messages that appear as the management console exits. 


These error messages can be caused by any of the following actions:
  • You are trying to connect to Tableau Server using a short name or a URL that is not the common name on the SSL certificate.
    • Verify the common name on the certificate. When accessing Tableau Server, use the name listed in the “Issued to” section of the certificate rather than the short name you used previously.  
  • The SSL certificate is not signed by a trusted authority or is not installed in your browser.
    • Verify that the certificate has been installed in your browser. For example, in Internet Explorer (IE), this should be installed in the "Trusted Root Certification Authorities" folder.
