Grafana camera idle

Configuration
1

I want to display some graphs in my dashboard (lovelace-ui)
I followed the instructions found here : Complete guide on setting up Grafana/InfluxDB with Home assistant using official Docker images

In configuration.yaml I have

camera 8:
  - platform: generic
    name: Grafana Power
    still_image_url: http://taditadida.duckdns.org:3000/d/JzhkcEggk/energie?orgId=1&from=now-24h&to=now
    
    username: usrname
    password: pwrd

and in lovelace-ui

  - title: Energie
    cards:
    - type: custom:mini-graph-card
      entities:
      - entity: sensor.power_consumption
        name: Actueel verbruik

When I use the url in a browser the grafana-dashboard will be displayed
the state of this entity remains idle :

access_token: fe76beb21ba0af0xxxxxxxxxxxxxxxxxxxxxxx3697876bdc1989
friendly_name: Grafana Power
entity_picture: /api/camera_proxy/camera.grafana_power?token=fe76beb21ba0af0b56xxxxxxxxxxxxxxxxxxxxx97876bdc1989
supported_features: 0

The token must have been automatically created because I did not do anything to it.

What do I have to change ?

Are you able to fix it?

Yes, I did
But I do not completely remember what I all changed to make it work (sorry)

In ui-lovelace.yaml I have:

  - title: statistiek
    panel: true
    cards:
      -  type: iframe
         url: https://tadidadadi.duckdns.org:3050/d/zQHJGwIWz/stroom_per_minuut?orgId=1
         aspect_ratio: 50%

portnumber 3050 is forwarded to the same port on my Synology NAS .

lines in configuration.yaml are deleted.

I hope this will help
