I have followed the verry good guides out there regarding using Duck DNS and NGINX to enable secure remote access to my home assistant. The problem I have is that NGINX won't start. It gives me the following error message.
2025-11-10 21:47:06.390 ERROR (MainThread) [homeassistant.components.hassio] Failed to to call /addons/core_nginx_proxy/start - Can't start addon_core_nginx_proxy: 500 Server Error for http+docker://localhost/v1.51/containers/4c7b6c2273f0c86bc863ae72040040dcf073d3432b09cfc62e187c0a49626e/start: Internal Server Error ("failed to set up container networking: driver failed programming external connectivity on endpoint addon_core_nginx_proxy (606c298e628dbccd099b4aaaf0c28f6438d89ceaed29b5deb8c0763d40d17a75): failed to bind host port for 0.0.0.0:8123:172.30.33.3:443/tcp: address already in use")
This is all I have in my configuration.yaml
`# Loads default set of integrations. Do not remove.
default_config:
Load frontend themes from the themes folder
frontend:
themes: !include_dir_merge_named themes
automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml
http:
use_x_forwarded_for: true
trusted_proxies:
- 172.30.33.0/24`
Any idea what it can be?
