Think I have my duckdns config wrong

Here is my config file. It was working but does not any more. Any idea what I have missing/wrong?


# Loads default set of integrations. Do not remove.
default_config:

# Load frontend themes from the themes folder
frontend:
  themes: !include_dir_merge_named themes

# Text to speech
tts:
  - platform: google_translate

automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml

What or how does it not work anymore?

It works fine on mobile but not on desktop (and I am hard-wired into same network)

Is it http://homeassistant.local:8123 or http://192.168.0.10:8123 that does not work?
or both?

What URL/IP address is listed on the HA server output, when you connect a monitor to it?
