Quote from website listed above:
When attempting to log on to a remote FTP site, a 530 status code is encountered, resulting in an error message similar to one of the following examples:
530 Not logged in.
ERROR:> Not logged in.
STATUS:> Connection closed.
530 Login authentication failed.
ERROR:> Not logged in.
STATUS:> Connection closed.
530 Password rejected.

This error is usually accompanied by repeated requests for the FTP account username and password.
