504 FTP response code

Updated May 3, 2017


This article provides information on 504 FTP response code.


All Serv-U versions


A 504 response code can be sent in response to any command using a parameter that is not supported by the server. It is a permanent negative response, which means the client is discouraged from sending the command again since the server will respond with the same response code. Issuing the same command with a different parameter may result in a different response code.

Example response

504 Command not implemented for that parameter.
