Basically the script cannot make a FTP connection to the LFS server directory. Why this is not working only you know.

Concerning your personal messages, I rarely do personal messaging because 1 on 1 discussions takes too much time but;

You have to make sure you have a FTP server running. If you login with a FTP client like Filezilla for example that you can actually access/download the file host63392.txt ..

As far as I can see you run everything locally on your computer which is fine but maybe Windows Firewall is blocking all traffic for port 21. Or the FTP server isn't running , you are not talking about that at all. So like I said, you need to confirm yourself that a FTP connection is possible with a FTP client and that you can see and "download" the host63392.txt file.
