Generic camera "weerslag.nl"

Trying to move my Buienradar.nl lovelace camera to weerslag.nl, but the last isn’t showing an image.
What is going wrong?

Here’s my config:

#### this is working ####
  - platform: generic
    still_image_url: http://api.buienradar.nl/image/1.0/RadarMapNL?w=500&h=512
    name: xxx

#### this is not working ####    
  - platform: generic
    still_image_url: http://weerdata.weerslag.nl/image/1.0/?size=ani-8-Onweer-550x550&type=Freecontent
    name: xxxWeerslag

Somebody an idea to solve this?

It seems that you need to use https instead of http.

I didn’t test with the camera component. But when i add this as a lovelace card it works:

aspect_ratio: 120%
type: iframe
url: >-
  https://weerdata.weerslag.nl/image/1.0/?size=ani-8-Onweer-550x550&type=Freecontent

That works great!
Thanks for this workaround!!
