Browsing to http://developermedia.com/ causes exception

[Styxxy]

Browsing to causes an exception (underlying connection is closed).

When testing .NET Standard and .NET Core (see issue #189 ), it actually works on .NET Core, but not on .NET Full.

var browser = new Browser();
var success = b.Navigate("http://developermedia.com/");
// success == false
// see browser.LastWebException

As of 20 July 2018, the unit tests are running without exception. Since we currently rely on public URLs for some online testing, this may be a temporary situation. I'm going to close this issue. If the test start failing again, we can re-open it.
