FTP service delay to respond

[dragnovich]

Hello I have a CentOS server in a cloud server, with plesk 9, Everything works perfect WEB, SSH and admin panel. how ever when I try to connect to the server using FTP clients like filezilla I cant get logged to FTP server.

Status: Connecting to 50.23.101.226:21...
Status: Connection established, waiting for welcome message...
Error: Connection timed out
Error: Could not connect to server
Status: Waiting to retry...
Status: Connecting to 50.23.101.226:21...
Status: Connection established, waiting for welcome message...

Checking the server the service ProFTPd is running, and working how ever, connecting directly from the server it, it take over 1 minute to get a responce, but once I get the login prompt I can login, and browse all ftp directories.

ftp cadenainmobiliaria.net
Connected to cadenainmobiliaria.net.

Googling I found that many users had similar problems, but fixed with correcting the /etc/hosts file how ever I did that and nothing got better.
