    Hi, MKamal.

    Would you please check what is the detailed CU version of your server?
    You can check it in the Control Panel>Programs and Features.

    If you are not on the latest CU version (CU19), it is recommended to upgrade to CU19 first.
    As CU updates will also include previous fixes for for security and nonsecurity issues.
