New description:

 I have used Cyberduck for months (registered user) and it's worked well,
 but now for some reason whenever I try to connect to FTP, FTPS or S3, it
 always connects and then immediately disconnects.

 I have tried reinstalling the application, but result is the same.

 example from log:


 {{{

 AUTH TLS
 234 AUTH TLS successful
 USER matt
 331 Password required for matt

 230 User matt logged in

 200 PBSZ 0 successful

 OPTS UTF8 ON
 200 UTF8 set to on
 SYST

 and another, same result, connects and then closes the connection
