Removing the ftplet worked. I was using it because I would like to capture
the output of the server to display in a status window and could not figure
out another way. Is there a better way to do that?

If you cannot debug the code, remove your FTPLet , set the debug level
to DEBUG and try and connect from a remote client while monitoring
the connection with wireshark.
