A month ago our WSUS server stopped syncing with Microsoft, we do have a proxy in use but we do not manage it and they said not changes were made. Below is the information on the errors we are seeing, any thoughts on what the issue can be?

Windows Server 2012 R2

Update Services
Microsoft Corporation
Version: 6.3.9600.18694

Even ID 10022
Event ID 7032:

The WSUS administration console was unable to connect to the WSUS Server via the remote API.

Verify that the Update Services service, IIS and SQL are running on the server. If the problem persists, try restarting IIS, SQL, and the Update Services Service.

System.Net.WebException -- The request failed with HTTP status 401: Unauthorized.

    Hi josephpatrick-7433,

    It seems that the Windows Server 2012R2 missed some important updates. Please help to confirm whether the KB4022720 has been installed on the WSUS server or not. If it wasn't installed, please consider installing this first.

    Note that the KB4022720 has been replaced on the following updates:
    2017-07 Security Monthly Quality Rollup for Windows Server 2012 R2 for x64-based Systems (KB4025336)
    2017-08 Update for Windows Server 2012 R2 for x64-based Systems (KB4039871)
    2017-07 Preview of Monthly Quality Rollup for Windows Server 2012 R2 for x64-based Systems (KB4025335)

    Reference picture:

    We may try to resync again after installing this update successfully. If there are any updates about this issue, please keep us in touch.
