Data connection cannot be opened with this PROT setting

Hello,

I am trying to set up FTP deployment. I have progressed as far as to make "Test FTPS connection..." and "Autodetect" root path work. Password and login are passed ok. However, the "Remote host" pane is empty (only the name of the server is shown, no directories underneath), and when trying to do "Compare with Deployed Version on ***", I get "Remote file *** does not exist". The log reads:

What does it mean and what should I do? Thanks in advance!

UPDATE: I have noticed that FileZilla issues a command "PROT P" which I cannot see in the phpStorm log. Can I make phpStorm use the private mode? Does it know about the protection modes at all?
