Estou tendo problemas para renovar meu certificado para minha instância do Nextcloud com o letsencrypt no meu servidor do Ubuntu 16.04.
Aqui está minha conf de renovação:
# renew_before_expiry = 30 days
version = 0.22.2
archive_dir = /etc/letsencrypt/archive/cloud.example.com
cert = /etc/letsencrypt/live/cloud.example.com/cert.pem
privkey = /etc/letsencrypt/live/cloud.example.com/privkey.pem
chain = /etc/letsencrypt/live/cloud.example.com/chain.pem
fullchain = /etc/letsencrypt/live/cloud.example.com/fullchain.pem
# Options used in the renewal process
[renewalparams]
post_hook = service apache2 start
installer = apache
account = a57eab015444b60984498d853e6c3531
authenticator = webroot

pre_hook = service apache2 stop
#server = https://acme-v02.api.letsencrypt.org/directory
[[webroot_map]]
cloud.example.com = /var/www/nextcloud/

Attempting to renew cert (cloud.example.com) from /etc/letsencrypt/renewal/cloud.example.com.conf produced an unexpected error: Failed authorization procedure. cloud.example.com (http-01): urn:ietf:params:acme:error:connection :: The server could not connect to the client to verify the domain :: Fetching http://cloud.example.com/.well-known/acme-challenge/fFCxCpEYRDWwBY0PMgAVljisoVdnc5wer6TblEA5pk8: Connection refused.

Isto é o que eu recebo quando estou executando curl -I http://cloud.example.be/.well-known/acme-challenge/
HTTP/1.1 200 OK

Então, o http - > O redirecionamento https (consulte a configuração do apache) está fazendo seu trabalho, exceto o diretório /.well-known/acme-challenge , para que o certbot possa verificar pela porta 80.
O que mais poderia estar errado para receber essa mensagem de erro?

To fix these errors, please make sure that your domain name was entered correctly and the DNS A/AAAA record(s) for that domain contain(s) the right IP address. Additionally, please check that your computer has a publicly routable IP address and that no firewalls are preventing the server from communicating with the client. If you're using the webroot plugin, you should also verify that you are serving files from the webroot path you provided.
