Problem with duckDNS & NGINX Home Assistant SSL proxy

Hi to all, i’ve managed to install duckdns and NGINX and properly configured those addon, then i’ve forwarded the ports 443 & 8123 to the respective ones of the of the home assistant from the modem page but i cannot access them over the internet.

What can i do to fix this?
The certificates are reporting correctly my duckdns address and the duckdns addon updates the IP correctly (because it’s the same one that plex uses so i was able to compare them easily) but when i try to access home assistant from anywhere but locally i get a “connection refused” error.

# Configure a default setup of Home Assistant (frontend, api, etc)

  internal_url: ""
  external_url: !secret https_address

  ssl_certificate: /ssl/fullchain.pem
  ssl_key: /ssl/privkey.pem
  ip_ban_enabled: True
  login_attempts_threshold: 3

this is my configuration.yaml file

I have recently with update my HA, i have now problems to have external access to home assistant.
It’s not the problem with my router.

I tried a lot but i can’t get it to work anymore.
My setup: Ubuntu server, Docker, HA with addons NGINX Home Assistant SSL proxy & DuckDNS installed.

My config file in HA;
use_x_forwarded_for: true
ip_ban_enabled: false
login_attempts_threshold: 8 ’

Does someone have the same problemens?
What can i do? Is it a problem with docker?
