For some reason the FTP server I'm connecting to seems to close the
session for no specific reason - here shown with a 426 error, that
currently my code is ignoring and hence I then get a later problem 530.
From my FTPClient logs

I notice that if I use wget, the same happens, but that automatically
reconnects and carries on as if nothing had gone wrong.
From the wget logs
==> CWD /pub/HireTRACK NX/autoupdates/HireTrack NX/3.0.1.169 ... done.
==> PASV ... done. ==> LIST ...
Error in server response, closing control connection.
Retrying.

My question is whether FTPClient component has this reconnection and
retry option already built in (and I just need to activate it by setting
a property) or whether I need to code it up myself ?
Don't want to unnecessarily reinvent the wheel.
