Swann CCTV DVR access stopped working on IE11 today

Really odd problem today.

I got my wife's laptop running on win 10 over the weekend, and one of the jobs was to also get it working with my Swann CCTV DVR which requires an active-x control.  That was pretty easy by opening the webpage to the DVR, and then clicking on open as Internet Explorer, and do the usual security tweaks to get the active-x control installed.  All tested and working reliably....until I ran windows update a couple of hours ago, and now the webpage from the DVR won't even load, let alone the active-x control.

All I get is a "This page can't be displayed" message.

So, I went to my own desktop machine (Windows 7/IE11) and found I have exactly the same problem on that. I haven't accessed the DVR on that for a few weeks so I can't be certain when that stopped working.  I note there was a cumulative security update for IE11 installed on the 9th of the month so that is where my finger of suspicion is currently pointing.  

I can ping the DVR from both the affected IE11 machines.

I have Swannview apps on iPad and Android to get in remotely and both those are working absolutely fine.  I then dug out my wife's old laptop I use for testing (IE9/Vista) and I can get to the DVR without any issue at all on that, so I know there is nothing whatsoever wrong on the DVR side of things.   

The DVR is accessed on port 3100 so all I can think is either an update to IE11, or some other update, is actually blocking the connection completely.  The reason I say "some other update" is I have noticed that if I access the DVR on a non-supported browser such as Chrome or Firefox on the old IE9/Vista machine, I still get the Swann logo page up even though it can't handle the active-x control.   If I try that on either of the two affected machines, I get page cannot be displayed type message on those browsers too.

Any ideas before I start uninstalling updates?

Thanks.

Have uninstalled KB3139929 - the most recent security update on my machine - and that made no difference.

Well, the problem cleared all by itself one day a few months ago so I can't be sure what the issue was. It still doesn't work 100% of the time on IE11 - sometimes it just hangs with browser not responding - but it was like that prior to this issue surfacing. 

I've since upgraded my own machine to win10 and found the EDGE browser a bit flaky in general, so installed google chrome and tried the IE tab plugin which emulates IE.  

That works REALLY well 100% of the time.  No hangs, no lockups, just does its thing. 

I can only assume because the DVR is a few years old now that it doesn't get on that well with real IE.
