Hello, I follow this tuto : https://www.howtoforge.com/tutorial/perfect-server-ubuntu-18-04-nginx-bind-dovecot-and-ispconfig-3/ Unfortunately Nginx doesn't listen on port 443 and I'm not be able to enable HTTPS and HTTP2. vhost file is created but without any ssl option. Have you a idea ? it's a certbot issue ? certbot log : Code: certbot.errors.FailedChallenges: Failed authorization procedure. www.jimbo.advertis.cloud (http-01): urn:ietf:params:acme:error:dns :: DNS problem: SERVFAIL looking up CAA for advertis.cloud, jimbo.advertis.cloud (http-01): urn:ietf:params:acme:error:dns :: DNS problem: SERVFAIL looking up CAA for advertis.cloud but Code: dig SOA jimbo2.advertis.cloud +short s1.advertis.cloud. 2019012701 7200 540 604800 3600 Regards
SSL is not enabled when there is no SSL cert and as the error message says, a Let's encrypt SSL cert could not be retrieved from Let#s encrypt. Probably your domain advertis.cloud as a CAA record which forbids LE certificates for this domain and it's subdomains.
thanks I fixed it ! A entry was missing for advertis.cloud certificat generate and ssl enabled thanks
