Cox disables port 80; certbot cannot issue letsencrypt certs because of challenge issue

[derekcentrico]

Okay, so I was stressing all day trying to figure out just what is wrong for NPM to not generate certs.

"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."

This wasn't really helpful until it dawned on me to see if Cox permits port 80. It does not.

Certbot, in NPM's setup, seems to only use http:// (80) to do the challenge verification. But, Cox would only permit it to occur on https:// (443).

Searching for a way around this but without success.

How can I workaround this issue so that I can setup NPM to have https:// access to my other docker containers?
