426 FTP response code

Updated May 3, 2017


This article provides information on 426 FTP response code.


All Serv-U versions


A 426 response 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.

Example response

426 Connection closed; transfer aborted.
