core_letsencrypt is not using the exposed port config key when http challenge is selected

[alefab]

Describe the issue you are experiencing

Even if the config key to change the external port is setup, the url used to validate the installation is not using it:

Same problem. I have port 8000 configured, but the logs report:

Hint: The Certificate Authority failed to download the challenge files from the temporary standalone webserver started by Certbot on port 80.

I did this today. The port you configure changes what port the add-in listens on, not what port the certbot uses. No idea if this is by design or not, but I simply worked around it by forwarding port 80 on my router to port 8000. It worked.
