@47210734
Thanks for your posting on Q&A.

I have noticed this link. It seems that the Windows Server 2008R2 missed the KB4484071 update. Please install the update on the WSUS server first and then confirm whether the issue will be resolved or not.

I'm sorry that I don't have the related environment for test. Please feedback to me if there are any updates. In addition, it seems that the Windows Server 2008R2 end of the support. It is recommended to upgrade to the later version.

Please keep us in touch if there are any updates of the case.

Thanks for your time and have a great day :)

Regards,
Rita

There was a similar sync failure for Windows 2008R2 WSUS back in February 2021:

https://docs.microsoft.com/en-us/answers/questions/264560/wsus-update-errors-since-2021-02-04-065644560-utc.html

There were comments then about having missing KB files, but in the end the failure was fixed by Microsoft with no intervention needed from WSUS administrators.

Would be useful if someone from Microsoft could find out what happened last time and see if this is the same problem.
