Can't connect to any website for which Flash Player settings open and request permission
(In advance, please excuse me when I make mistakes with terminology; I'm totally new to this.)
Using Windows10 Home Version 1709.
Windows64-bit,English, I've tried with the same results using Chrome, Internet Explorer, Edge, Firefox browsers
Adobe Flash Player version 27.0.0.187
Well, for the past couple of weeks I haven't been able to broadcast or even establish a connection with websites after the Flash Player Settings open requesting permission for the website to access my camera and microphone.
This is the instructions from one of the websites I'm having trouble with. Nothing is clickable except "Next Step".


When I click "Next Step", I'm carried through a couple more instruction pages then


Now, you can see it's the same in different browsers. When I click "allow" the dialogue immediately closes but doesn't actually let me adjust any settings, and I just get a "Can't connect to the website" message
In Chrome it looks like this and there's a speed test

in the above pic you can see a link to a speed test - if I click I get:

In Firefox

Each browser is just a little bit different, but basically the results are the same - I can't get a connection to the site with the Flash
I have meticulously gone through the settings in each browser and enabled Flash Player.
I have a really fast internet and i even plugged in the ethernet cable just in case of any problems with my wifi.
Also tried a few other websites that broadcast live and it is the same thing...
I used to be able to connect and interact with these sites, never had this problem before, the only thing that changed is that I did reinstall Windows 10 according to the direction of Microsoft support reps. I have chatted with Microsoft support for HOURS and those guys have no answers. (They finally recommended asking Adobe Support.) I've also chatted and emailed back and forth with the support teams from the individual websites. All the troubleshooting and still no results. Can you help? I'm totally stuck. Thank you.
Oh yeah, if I right click on the gray screen I get this Chinese stuff - (yes this time it's IE)
