Maybe they don't like Firefox? Or Windows? Or the combination? And this is
not a joke. I did five tests in parallel:
- Windows 7 with Firefox 47,
- Windows 7 with IE 11 (the same VM),
- Mint 17 with Firefox 48,
- OSX 10.6 with Safari, and
- Windows XP with IE6 (OK, that poor guy was failing to render, but the connection was not reset).
Guess which one was
the only one getting a "The connection was reset"? For both websites that you gave me the link to? To be more accurate, the page seemed to be loading at first, and
then it was getting an error. Both sites seem to do a constant refresh of sorts. I will not get in the trouble of analyzing their code.
There's no apparent reason for some sites to fail, unless the site wants (or doesn't know how to avoid) to fail. VirtualBox doesn't play nice with some OSes and some applications, while not others. Websites on the other hand, have been notorious about such foul behavior.
