 Whenever I queue up a whole folder or a large batch of files to download
 via FTP, usually when backing files in prep for a WordPress update, I
 ALWAY get this error below, and it always happens on EVERY SERVER from
 different hosts. It does not matter if I use Passive or Active
 connections. I have opened up the server timeout to the full 120
 seconds... and let me be clear, CYBERDUCK APPEARS TO DOWNLOAD THE FILES
 AND GOES THROUGH THE ENTIRE DOWNLOAD PROCESS, and it is not until the very
 end of the download that I get this error, AND in most cases the FILES
 DON'T SEEM TO BE DOWNLOADED EVEN THOUGH CYBERDUCK LOOKED LIKE IT DID!

 '''Error: Connection failure:
 FTP response 421 received.  Server closed connection. The connection
 attempt was rejected. The server may be down, or your network may not be
 properly configured.'''


 My only workaround is to download smaller batches of files which is
 absolutely too time consuming and a complete nuisance! What is causing
 this?
