This is a sign of a likely firewall, either at the client or host end. Strict
firewalls don't let arbitrary TCP connections through, and since this
ftp connection is encrypted, deep packet inspection doesn't help. Try the
--ftp-ssl-ccc option to send the control connection in the clear, or try the
--ftp-port option to make the data connection be initiated from the server
instead of the client.
