Getting errors as well. Neither Google Chrome, nor Microsoft Edge nor IE manage to open the download web page. ERR_SSL_PROTOCOL_ERROR is what I get on modern browsers, but IE gives a bit of a different story
There was a temporary DNS error. Try refreshing the page.
Error Code: INET_E_RESOURCE_NOT_FOUND
I am using Google DNS, so that should not really be an issue. There isn't really anything that should be blocking a properly set up webpage either on my PC or my network. The only things I am running are Windows Defender and Malwarebytes antimalware. Otherwise it's a bog standard network setup.
