I still have the same problem:FileZilla connects using FTPES, FTP over explicit TLS/SSL (but not FTPS, FTP over implicit TLS/SSL).
I have the username and password in the ftp.cfg file. If I include them on the command line, I get the same message.
If you google the error message, you'll find it in a number of unrelated places.>TCC: 534 Fallback to [C] "www.ping-pong.biz"
OK. That's interesting. But, FileZilla keeps going after getting that message, while TCC gives up. Here is the FileZilla log:On Tue, 15 Jul 2008 18:16:20 -0500, David Marcus <> wrote:

I found this explanation at
Such error typically looks like:
COMMAND:> PROT P
534 Fallback to [C]
Some SSL/TLS secure FTP servers don't allow user to do encrypted data transfer
(i.e. initiated by LIST, RETR, STOR, etc), and only allow a secure command
channel. For this reason you need to use non-encrypted data channel when
connecting to these servers. Go to [Site Settings | Security] and select
checkboxes [Clear file data transfer] and [Clear listing data transfer]. Then
"PROT P" asks for "Private" data channel protection level. According to RFC>OK. That's interesting. But, FileZilla keeps going after getting that message, while TCC gives up.
