Certbot failed to authenticate some domains (authenticator: webroot) : Connection refused

Help

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: makaveli.kiosquelitteraire.org

I ran this command:

docker run --rm \
  -v /var/www/greencheck/backend/certbot/www:/var/www/certbot \
  -v /var/www/greencheck/backend/certbot/conf:/etc/letsencrypt \
  certbot/certbot certonly \
  --webroot \
  --webroot-path=/var/www/certbot \
  --email nzanzu.lwanzo.work@gmail.com \
  --agree-tos \
  --no-eff-email \
  -d makaveli.kiosquelitteraire.org \
  -d www.makaveli.kiosquelitteraire.org

It produced this output:


Certbot failed to authenticate some domains (authenticator: webroot). The Certificate Authority reported these problems:

Hint: The Certificate Authority failed to download the temporary challenge files created by Certbot. Ensure that the listed domains serve their content from the provided --webroot-path/-w and that files created there can be downloaded from the internet.

Some challenges have failed.

Your system is refusing HTTP (port 80) requests coming from the public internet.

You didn't describe what web server you were using (Apache, nginx, other?) but usually that is what would reply to those requests.

This isn't unique to Let's Encrypt. A check from many places world-wide are all refused. Check firewalls, network configuration, and any port routing to/from your container.
