    I have the same issue. Key expiration is shown as • May 2 2020 (today is 7 May) but there is no • Next license key update. Selecting the Retrieve Keys option as per the warning message instructions returns this message:

    Key Update Status

    Unable to connect to license server https://ka.plesk.com/xmlrpc.
    cURL error description: Could not resolve host: ka.plesk.com; Host not found(6)


    And the email response to the above says this

    Hello John Lloyd

    This error message means that your server is unable to resolve the hostname of ka.plesk.com.

    Please, check the network settings of your server and make sure that DNS server is set. If not, you may use (Google DNS server).

    In case this wouldn't help, follow recommendations from this article: https://support.plesk.com/hc/en-us/articles/115000256834
