Certificat SSL proFTPD

J'ai fait quelques recherche sur l'outil internet pour avoir réponse à ma question, mais ça a bien foirer.

J'ai déjà regardé sur plusieurs sites, et c'est toujours la même chose, j'ai une erreur.
Et je ne trouve pas la solution..

Oui déso..

J'ai suivi des tutos sur ces sites (malgré qu'ils se ressemblent un peu):

https://doc.ubuntu-fr.org/proftpd_et_tls_ssl
https://www.howtoforge.com/tutorial/install-proftpd-with-tls-on-ubuntu-16-04/#-enable-tls-in-proftpd
https://websiteforstudents.com/configure-proftpd-use-ssltls-certificates-ubuntu-17-04-17-10/
https://www.barrekevin.com/2018/05/23/installation-serveur-ftp-proftpd-ssl/

Et oui, les tentatives de connexion se font en local, avec FileZilla.

Je ne sais pas quelle version je dois t'envoyer.
-Soit la version avec les options pour le SSL
-Soit la version sans SSL.

Comme je veux accèder à mon serv (même sans sécu (pour l'instant)) j'ai remis le fichier sans SSL, ce qui donne:
