The problem seems not in SSL but in TCP/IP level.
DeleGate says that it simply failed to establish TCP connection to the
port on the server which was shown in the response for a PASV command.
You can get detailed log with "-vd" option which shows the dialogue
between the DeleGate ant the server including the PASV command/resopnse.
Seeing the log of the FTP server and "netstat -an" on the server's host
will be helpful.

By the way, are you sure that your FTP server (what is it?) works without
problem with FTPS clients other than DeleGate?

Cheers,
Yutaka
