For that to happen, the client is trying to connect to an IP/Port that does
not actually have a server listening on it. Is there a firewall or router
between the client and server, by change? Either one of those could be
altering the data that TIdFTPServer reports. Or, in the case of a router,
you might not be proving the server's actual public IP/Port in the
OnPASVReply event. Can you show the actual command/reply data that is being

It should be. TIdFTP sends the PASV command to the server before creating
the DataChannel socket that will handle the transfer. TIdFTPServer opens a
listening socket immediately when it receives the PASV command.

Please show your actual server code, and the low-level FTP command/reply
data that is being transmitted.
