Displaying youtube vid in collapsible row

Hi,

I want to display a youtube video in a collapsible row on my product page.

I use metafields for the url and put the following code in “main-product.liquid”

{% if block.settings.heading == 'Experten testen - Produktvideo' %}
  <div style="position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden;">
    <iframe style="position: absolute; top: 0; left: 0; width: 100%; height: 100%;" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope;" allowfullscreen src="{{ product.metafields.custom.product_page_video_html }}"></iframe>
  </div>

However, on the front end, there is an error message, which says that the domain has resfused the connection:

Does anyone have an idea how to fix this?

Does anyone have any idea how to solve this?

I am actually looking for the same solution, I did found this but I did not had the time yet to figure out if it works.
