Solution
The problem is due to the proxy server you are trying to use. It does not have the "Connect" method enabled. SmartFTP only supports the http proxy "Connect" method. The proxy works fine in Internet Explorer since it uses the "GET" method that treats the FTP like a web page. SmartFTP does not support this method. In order to use SmartFTP with your proxy, the proxy server needs to be reconfigured to support the "Connect" method.
