DuckDNS - port forwarding

On my marble 3000 glinet router, i port forward the in and out ports to 443
Objective is to have duckdns setup on my hardware device homeassistant to run locally. I then added NGINX to register the domain from duckdns but its being sent to my routers ip not home assistant?

What have i done wrong...

Is your port forwarding correct?

Port forwarding will only work from outside of your network. Please test via mobile phone, for example.
