Have installed proFTPD from webmin and it works…
Then I would like to support FTPS
command line
apt-get install openssl
mkdir /etc/proftpd/ssl
cd /etc/proftpd/ssl
openssl req -x509 -nodes -days 9999 -newkey rsa:2048 -keyout private.key -out public.crt
/etc/proftpd/proftpd.conf
<IfModule mod_tls.c>
TLSEngine on
TLSLog /var/log/proftpd/tls.log
TLSProtocol SSLv23
TLSOptions NoCertRequest
TLSRSACertificateFile /etc/proftpd/ssl/public.crt
TLSRSACertificateKeyFile /etc/proftpd/ssl/private.key
TLSVerifyClient off
TLSRequired on
</IfModule>

Best Answer
Port 22 is ssh. Which means you are trying to use sftp (file transfer over ssh) and not ftps (ftp with ssl). But with proftpd you have to use either ftp or ftps.
