Issue

Unable to authenticate with SSL Tableau Server from Tableau Mobile, the following might occur:
This server doesn't support secure communication...

Additionally, when attempting to sign into Tableau Server through the mobile android device, the following error message might occur:
Cannot connect to this server. Contact your administrator to make sure it is online

Environment

  • Tableau Server 9.3
  • Android
  • SSL

Resolution

Work with your IT team to verify the SSL certificate on the mobile device per manufacturers instructions.  You may also need to check the validity of the certificate chain between the device and Tableau Server.  

Cause

The mobile device may not have SSL certificate installed or a trusted chain.

Additional Information

Signing in via a mobile browser will likely be successful if SSL is implemented successfully on the Tableau Server, but may fail using the Tableau Mobile App. The SSL certificate is often downloaded automatically for use in the browser but must explicitly be installed for the Tableau Mobile App.
