Unable to connect to FTP server with this combination of details.

530 Login incorrect.

the only thing i am unsure of in the settings is the local host thing and the port.But the other three i am certain  that i am correct.

If localhost doesn't work, try ftp.yourdomain.com. If that still doesn't work, try ftp.yourhost.com. The port is almost always 21.
