Since the beginning of 2019 Plesk started to report to their partners about the licenses installed on more than one physical or virtual server at once. Such licenses violate Plesk End User License Agreement (EULA) and therefore, they are automatically marked as “fraudulent”. Openprovider, being a Plesk Platinum partner, is obliged to follow Plesk's recommendations and has changed its internal processes and license use policy accordingly.
Fraudulent licenses termination
Licenses that are used on more than 1 server (more than 1 IP address is detected with the same license applied) will be automatically terminated. This is done to prevent multiple billing of the license since Plesk is now charging for every IP address detected with the license.
If you receive such notification you should replace the licenses mentioned on every Plesk instance which uses the fraudulent license to minimize the impact on your end customer websites.
No license download option
It is no longer possible to download the license key as an XML file from Openprovider control panel or via API.
This is done to enforce using activation code for license installation on the server. When a license is activated via an activation code it is automatically registered at Plesk Key Administrator and its usage is prevented on more than 1 server. It will not be possible anymore to activate Plesk instance without having a public IP on the server instance.
License activation code can be retrieved from Openprovider Control Panel license details page or via API.
