Problem of connecting to ftp

Hi all,

I recently installed Sentora on a dedicated CentOS 7.2, 64 bits, and I have a problem with connecting FTP, I can not connect in any way with either FileZilla or Cyberduck. I tried to install the Monsta File Manager module and I can not access the ftp.



The error in FileZilla is the following: 
Status: Connecting to 163.172.209.124:21...
Status: Connection established, waiting for welcome message...
Status: Insecure server, it does not support FTP over TLS.
Command: USER zadmin_admin
Response: 331 Please specify the password.
Command: PASS **********
Response: 530 Login incorrect.
Error: Critical error: Could not connect to server
