Effortless encryption with Let's Encrypt and DuckDNS

Hi!
@DavidFW1960 seems like you know about the config.

I have a working duckdns. I generated no problem the SSL.

I did a port forwarding from external 8123 to interal 8123 with the pi internal ip.

Checked that the ip in duckdns was correct with another tool (what is my ip) and it matches up.

I added in my configuration.yaml the following:

http:
  base_url: https://specialurl.duckdns.com:8123
  ssl_certificate: /ssl/fullchain.pem
  ssl_key: /ssl/privkey.pem

(obviously specialurl is not the real section)

still i get " This site can’t be reached" when i enter in the browser https://specialurl.duckdns.com:8123

any ideas?
