    Please try the following troubleshooting:

    • Check if the license key pack ID is valid and not expired.
    • Ensure that you have the correct version of the Remote Desktop Licensing Manager installed.
    • Check if the Remote Desktop Licensing service is running.
    • Ensure that the server is connected to the internet and can communicate with the Microsoft activation servers.

    Hope the information is helpful.
