------------------------+-------------------
 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:

 220 ProFTPD 1.3.4c Server (ProFTPD) [64.207.188.195]

 234 AUTH TLS successful

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