fullchain.pem : le certificat SSL et la chaine de certification concaténée
privkey.pem : la clé privée
/!\ La clé privée ne doit jamais être divulguée à un tiers.

Ouvrir les ports 80 et 443 pour générer le certificat
Les ports ne doivent pas être utilisés. pensez a stopper Nginx par exemple.

/!\ Si plusieurs domaines on peux générer un seul certificat pour l’ensemble, il faut les rajouter a la suite.
Exemple ./letsencrypt-auto certonly –standalone -d monserveurmail.domaine.tld -d monserveurproxmox.domaine.tld
