My domain is: monoviajero.com I ran this command: lego --tls --email="my@email.com" --domains="monoviajero.com" --domains="www.monoviajero.com" --path="/opt/bitnami/letsencrypt" renew It produced this output: 2019/12/02 20:37:36 [INFO] [monoviajero.com] acme: Trying renewal with -48 hours remain…

I still see nginx on IPv6 port 443. I’ve tested from multiple locations. That IPv6 address is owned by 1&1, not EC2. Are you really sure it’s correct? Even the port 80 response is not correct: $ curl -X GET -I -6 http://monoviajero.com HTTP/1.1 403 Forbidden Content-Type: text/html Content-Length…

Regarding Nginx response maybe your request was made just when lego is running because in my case the same requests obtain the following results (when Apache & Wordpress is running): …

You have a right ! I just see here the following warning: Fatal: Check of /.well-known/acme-challenge/random-filename has different answers checking ipv6 / ipv4. Ipv6 doesn't have the expected result http status 404 - Not Found. Creating a Letsencrypt certificate via http-01 validation may not wor…

You made my day !!! Finally the problem was with bad IPv6 AAAA record. Just after removing AAAA records from DNS, certificate renews without any problem. As shown in warning that I posted before, LetsEncrypt prefers IPv6 instead IPv4. Thanks a lot for your help !!!
