Example Reply
426 Connection closed; transfer aborted.

A 426 reply code may be sent in response to any command requiring the usage of a data connection. It is considered a transient negative reply as it is considered to be a temporary condition. It is usually sent when the data connection is unexpectedly closed before the completion of a data transfer. In this case, the client is encouraged to restart the FTP transaction and try again.
