Parallels Plesk Panel daily maintenance script establishes a connection with the Parallels Licensing server and initiates periodic license update procedures based on the current date and the last update time from the /etc/sw/keys/registry.xml file. A successful license update procedure will update the /etc/sw/keys/registry.xml file with the new license update time.


Parallels Plesk Panel is sending a key update deferral notification (as below) even after the valid license key of Parallels Plesk Panel has been installed:

Subject: Parallels Plesk Panel key update deferral notification
Unable to update. An error occurred while processing your key. You can try to update it later.


When the license update procedure fails, the above notification is sent.
