Failed authorization procedure. www.aftercoffeedesigns.com (http-01): urn:ietf:params:acme:error:connection :: The server could not connect to the client to verify the domain :: Fetching https://aftercoffeedesigns.com/.well-known/acme-challenge/BdqUVG03sKdgTTqJ5sCXhxAD9dWnBBlNxqD-kqKCQzM: Error getting validation data

IMPORTANT NOTES:
 - The following errors were reported by the server:

   Domain: www.aftercoffeedesigns.com
   Type:   connection
   Detail: Fetching
   https://aftercoffeedesigns.com/.well-known/acme-challenge/BdqUVG03sKdgTTqJ5sCXhxAD9dWnBBlNxqD-kqKCQzM:
   Error getting validation data

   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.

I used this instructions https://www.digitalocean.com/community/tutorials/how-to-secure-apache-with-let-s-encrypt-on-ubuntu-16-04
I pick the option that for https only.

Any suggestions ?
