Hi,
Thank you for posting in Microsoft Q&A forum.
1,May we know many clients are facing this issue?
2,How do you deploy the update, through WSUS/Intune or Windows update? This error generally means that the Windows Update Agent was unable to connect to the update servers or your own source, such as WSUS, Configuration Manager, or Microsoft Intune.
3,If you're using the public Microsoft update servers, check that your device can access the following Windows Update endpoints:
http://windowsupdate.microsoft.com
https://*.windowsupdate.microsoft.com
https://*.update.microsoft.com
https://*.windowsupdate.com
https://download.windowsupdate.com
https://*.download.windowsupdate.com
https://download.microsoft.com
https://*.download.windowsupdate.com
https://*.wustat.windows.com
https://ntservicepack.microsoft.com
Thanks for your time. Have a nice day!
Best regards,
Simon
