Select the License server entry in the category tree [Category].
-> The settings pages for the administration of the license server are displayed.
The Licenses Tabbed page is selected by default.
On this page you can check all data of your license server licenses, especially the status [Status], which should be green = Ok.
All valid hostids [Host ID] are displayed directly below the tabs, separated by "/". These were determined automatically.

Catalogs without a valid license are displayed under PARTadmin -> PARTsolutions -> Catalog update -> Online in a separate section Catalogs, no valid license.
