@Derrick-Johnson When I had issues with my company firewall/ssl certificates I downloaded the offline installer and it worked fine. From the page: http://www.qt.io/download-open-source/, click the "view all downloads" scroll down until you see the offline installers and pick the one that you need. When you run the installer it looks the same (i.e. type in your username / password, but it does not need to do the ssl handshaking).
