[Lynx-dev] Windows Defender ATP

[Gisle Vanem]

I just discovered the new features of Microsoft's
"Windows Defender Advanced Threat Protection".

Overview of all these features:
   https://demo.wd.microsoft.com/?ocid=cx-wddocs-testground

After enabling the interesting feature, 'Network Protection'
by:
  c:\> powershell Set-MpPreference -EnableNetworkProtection Enabled
  ref: https://demo.wd.microsoft.com/Page/NP

Then trying to fetch the test-page using Chrome, curl an wget, I
get a trace like this:
 c:\> wget https://smartscreentestratings2.net/

  --2019-01-29 14:54:23--  https://smartscreentestratings2.net/
  Resolving smartscreentestratings2.net (smartscreentestratings2.net)... 
23.99.0.12
  Connecting to smartscreentestratings2.net 
(smartscreentestratings2.net)|23.99.0.12|:443... connected.
  Unable to establish SSL connection.

  (and a WinDefender block warning window pops up).

But using 'lynx -dump https://smartscreentestratings2.net/', I'm
getting a seemingly valid connection and page is rendered as:
                               SmartScreen Test

  This is a test page for SmartScreen.

As if the 'Network Protection' was disabled. But I do get the
same WinDefender block warning window in addition to the page

What could cause the difference in behaviour?
My Lynx used OpenSSL, so does my Wget and curl
(with CURL_SSL_BACKEND=openssl)

Scratching head now!?
