Looks like just a delay/timing issue on Microsoft’s end. You’ll probably need to just try again until you get a successful download of the latest wsusscn2.cab file. I was just testing for the past little while without success, but then a moment ago I just got a successful download of the new wussscn2.cab file that has digital signature timestamp from just a few minutes ago (Thursday, May 11, 2023 10:50:59 AM), which means they *just* posted it. BatchPatch downloaded it and was able to scan for updates without issues.
