Cannot connect from external with smartphone

Mobile Apps Home Assistant Companion for Android
1

Hi , i don’t know what to try anymore!!
I have setup an address with duckdns.
With my Galaxy S8, when i’m on my local network , i can connect with the app or with Chrome no problem.
But as soon as i’m on external network ( let’s say LTE) i cannot connect.From external i tried Chrome,Webview, Firefox and the APP.
i get "Initializing " foreever, and if i refresh it say unaccessible or connection refused!!

here my config file :
# Configure a default setup of Home Assistant (frontend, api, etc) 
default_config:
 ##################################################
 # Text to speech
tts:
   - platform: google_translate
 
 group: !include groups.yaml
 automation: !include automations.yaml
 script: !include scripts.yaml
 scene: !include scenes.yaml
 
 http:
   ssl_certificate: /ssl/fullchain.pem
   ssl_key: /ssl/privkey.pem
   
 homeassistant:
   external_url: https://MY-IPms.duckdns.org:8123

Port forwarding done in Router

What am i missing ?

check if your internet provider uses ipv6 / ipv4. mobile & router. both protocols cannot be combined. either the connection is used via ipv4 or ipv6. you can set this in duckdns.

Thanks ,i guess i’ll have to read some more, i don’t know how to set it in duckdns and i can’t find which ipv my mobile is using !!

Try out https://ipv6-test.com
Once by your mobile and by your local isp via WLAN.
Best regard
