Error "Tableau Server is unlicensed" After Rebooting Virtual Machine Hosting Tableau Server
Published: 06 Dec 2016 Last Modified Date: 20 Oct 2020
After rebooting the virtual machine hosting Tableau Server, the following error occurs:
Tableau Server is unlicensed.
Resolve the issue in the current instance by reactivating the license. For more information, see Activate Tableau.
Prevent the issue from occurring again. If Step 2 is not completed, an issue with exceeding maximum activations may occur in the future. There are two options for preventing Tableau Server from becoming unlicensed after a restart/reboot:
This resolution is the most reliable - please work with the hosting provider to ensure that the following factors remain static during a restart of the instance:
Virtual Machine ID
If you are unable to make the above factors static, the Tableau Server license must be deactivated before restarting the instance. For example:
Before restarting the instance, deactivate the Tableau Server license
Restart the virtual machine
After a successful reboot, re-activate the license
When restarting an virtual machine instance, the Tableau Server license frequently becomes unlicensed because Tableau Server's license is linked to the hardware of the host, even with virtual machines. Some virtual machines will change physical hardware during an instance restart/reboot, which then breaks the licensing. For example, Amazon or Microsoft will assign an image to a new instance during restart in order to make the hardware available for updates or maintenance.
