Windows update error code 8000FFFF

We are using WSUS for updates. Last week I pushed out 2019-01 Monthly Security roll up for servers and desktops. Almost 1/3 systems had update failure with the same error code 8000FFFF, "Windows update encountered an unknow error", it happened on servers and desktops.

I did a lot of researches and there is nothing useful to fix this issue.

We never had any issue with WSUS pushing our updates

Anyone had the similar issue before? below part of CBS.log
