Hmm, very strange.
FSHostSpy uses the same Windows functions that Internet Explorer uses, so if you can connect with IE, you should be able to connect with FSHostSpy also. You said you connected with a browser -- was it IE? If not, does it work in IE?
Yes, the unfriendly list of numbers is what you should see at that address. That's the list of servers that FSHostSpy retrieves.
Also, let's check to see if IE is using any proxy settings. In IE, go to Tools / Internet Options / Connections tab, click the "LAN Settings" button and see if anything is checked there. Normally all checkboxes are unchecked. If any are checked, please tell me which ones, and which settings are being used with them.
Thanks,
Russell
