Read all file names on ftp server

I tried this code by inputting the ftp address as ftp//:***** and the correct username and password and I get the following error
"Unable to connect to the remote server" on line :

FtpWebResponse Response = (FtpWebResponse)Request.GetResponse();

I tired this on my ftp server provided by a hosting service and an anonymous ftp located at 193.166.120.5

Any ideas on this one?

Note: I was able to connect to both of these ftp through filezilla, via a webbrowser, and through windows command line.

Thanks
