 When connecting to an SSL/TLS server I get error '534 Fallback to [C]'
Solution 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 reconnect again.
