SFTP time out during connection

I'm trying to connect to an sftp server but I'm not able to get the connection.

The server and the credentials are ok because I can connect using an ftp app, so I was wondering if there's some option that I'm not doing well.

This is the config that I'm using

and I'm getting a TIME_OUT
