This is a common problem that occurs on all sites that use the https:// in the web page address. I have seen this problem exclusively on computers that are using Norton Internet Security or Norton Firewall.

The problem stems from corruption in the Norton software. Just uninstall the software and then reinstall. This has fixed my customers problems 100% of the time.

On the Internet, your computer communicates with other computers through ports. Think of a port as a conduit by which computers send information back and forth to each other. In the case of http:// vs https://, the https:// communicates on a different port.

The http:// communications on port 80 which is the default port for all Internet traffic. However, there are specialty sites and pages that need to work more securely such as https:// which communicates on port 443. For whatever reason, the Norton software becomes corrupt and then blocks traffic on port 443. You usually will receive “Page Not Found” error when the port is blocked.

You may also run into this problem when you are using a computer at different locations. Say for instance, you can reach a particular site while surfing at home; however, when you try to reach that same site from a location at work, you get the “Page Not Found” error. The reason for this problem is usually because corporate security has blocked the particular port you are trying to access. All web pages cannot be reached on port 80 even if they are not secure (https://) sites.
