WSUS on Server 2012 R2.
Was working OK yesterday, 28 June 2017.
This morning, 29th June, large number of clients (possibly all) are failing to communicate correctly, eg when attempting to do a manual "Check for Updates". Windows 7 (x86) and Server 2008r2 come up with 80244008. A windows 10 client (x64) and 2012r2
gave error 8024401f. The WSUS management console opens without any issues.
Last status report of any client into WSUS is 630am this morning, which appears to be about 10 minutes after a restart of the WSUS Server to install 2 MS Updates this morning. 4022720 (preview of monthly rollup) and 4037282 (update for Internet explorer).
I suspect one of those updates is the issue. I've checked the details of 4022720 and can't see anything obvious that would affect IIS or WSUS, nor guidance to run any post install steps. If necessary I can uninstall, but would prefer not to, as that would only delay the issue until middle of next month when the general release of what is in 4022720 is pushed out. I have, though re-run the steps from the update that came out a year ago.
Our server is configured to use port 80, so no SSL involved, but I'm wondering if something in one of the above updates has done something to affect this.
There are a few messages in Application log and other logs that may prove useful...

I can provide other logs later (eg WSUS logs, and logs off couple of the client systems too).
Thanks in advance
