Hi all,

When I sync software updates in SCCM console, it failed with the error message in wsyncmgr.log:

Sync failed: WSUS server not configured. Source: CWSyncMgr::DoSync

And I also checked the wcm.log:

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

Anyone can help me to fix the issue? Thanks in advance.

    Hi, @ige dan

    Thank you for posting in Microsoft Q&A forum.

    WSUS Configuration Manager configures the WSUS server once every hour. It does so to ensure that the settings configured in WSUS match the setting specified in the Configuration Manager console.

    If WCM fails to configure the WSUS server properly, synchronization attempts can fail with an error similar to HTTP status 401: Unauthorized.

    Synchronization may fail because of authentication or proxy issues.

    You may try to follow the steps in below article for troubleshooting:
