Not getting appdaemon to work

Here is my appdaemon.yaml

secrets: /config/secrets.yaml
log:
logfile: STDOUT
errorfile: STDERR
appdaemon:
threads: 10
app_dir: /config/appdaemon/apps
plugins:
HASS:
type: hass
ha_url: https://[email protected]:8123
token: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
hadashboard:
dash_url: https://ABC123.duckdns.org:5050
dash_dir: /config/appdaemon/dashboards

When I click on OPEN WEB UI I’m getting this message.

This site can’t be reached
ABC123.duckdns.org took too long to respond.
Search Google for everyhome duckdns org 5050
ERR_CONNECTION_TIMED_OUT

Any ideas?

Thx
