FTP users problem

Hello, since from beggining I have problem with FTP on my server.

Server is Debian 8.2 and Plesk 12.5.30 Update #20

I have no idea what can be...
At beggining I tried to set to use FTP root, and maybe that I something crashed...

Now, for every webspace I created, and FTP user for that webspace, I cant use FTP.
I tried FTP and SFTP, and ports 21 and 22, and Filezilla and WinSCP...
Only I can do, is upload over browser...

Can you help me, where to look, from what point to beggin?
