There is no way to reconfigure the ProFTPD configuration file when you messed up with the configuration file or uninstall the ProFTPD. I resolved the issue of not able to access FTP by reinstalling Sentora on a new aws instance. As I messed up the configuration file of ProFTPD.
One note to newcomers - The FTP server which is used by Sentora is ProFtpd, not vsftpd. Before installing the Sentora on your server properly go through the documentation. It will save you from a lot of pains if something goes wrong.
