    Hi,
      

    This problem occurs because the WSUS application on the server is not SHA2-compliant.
    To fix this problem, download and install Update for Windows Server 2008 R2 for x64-based Systems (KB4484071) that was released on November 12, 2019. 
    For specific details on this fix, please refer to the article provided by Microsoft: "WSUS does not sync with Microsoft on WSUS 3.0 SP2-2008 R2 servers because of certificate error."
       

    Hope the above can help you.
       

    Regards,
    Yic
