Hassio, DuckDns, Airport Extreme

Good evening everyone! I’m new to HASSIO but I appreciate the ease of use and the excellent GUI
My home network is managed by an  Airport Extreme…
Without any problem, on the RB3b + I configured HASSIO and then the KNX devices of my house and made them visible and fully functional in Homebridge
During Black Friday, I bought a Google Home and now I would like to configure it (I’ve seen the tutorials, it’s not difficult at all)
My huge problem (I never thought so!) Is related to the DuckDns platform.
I followed step by step more tutorials, the best I thought is this


I’m literally going crazy for two days, I checked and double-checked the steps, the configurations but I still can not connect with DuckDns. Locally everything is ok and reachable via HTTPS

This is the HTTP in configuration.yaml

            api_password: MYPASSWORD
            base_url: !secret https_domain
            ssl_certificate: /ssl/fullchain.pem
            ssl_key: /ssl/privkey.pem

This is the configuration of DuckDns add on:

  "lets_encrypt": {
    "accept_terms": true,
    "certfile": "fullchain.pem",
    "keyfile": "privkey.pem"
  "token": "MYTOKEN",
  "domains": [
  "seconds": 300

In your opinion, is it possible / likely to be the Apple firewall that blocks the connection?
This is my port forwarding

Trying to connect via Safari to my DuckDns subdomain, it tells me
safari could not open the page because it could not connect to server…

Thank you for your invaluable help and support
