The proxy server is accessed via non-standard network ports; web traffic is normally sent on ports 80 and 443, but the proxy server uses ports 2048 and above. If your computer has a firewall it may be blocking some of the ports that the proxy server requires:

• Test for a firewall blocking port 2048.
• Test for a firewall blocking port 3331.
