Additional Information
Starting in Tableau Server 2021.4, when using ATR for the activation method (selected by default), there is a pre-install check to ensure the computer is able to reach the ATR licensing server. This takes place prior to actual activation of the license key. If the check fails, Tableau Server will not complete the installation and instead returns the attached error message advising the connection be checked.
Example error in the app-install.log:
2021-12-20 15:47:48.487 -0500 main : INFO com.tableausoftware.installer.operations.VerifyATRServiceOperation - ATR Service is not available.
2021-12-20 15:47:48.501 -0500 main : INFO com.tableausoftware.tabadmin.cli.Console -
Unable to activate Tableau Server using ATR for product activation because you are not connected to the internet. Check your internet connection and try again. If you are activating Tableau Server offline, rerun Tableau Server Setup with parameter 'ACTIVATIONSERVICE="0"'.
