Videos iframe error

I need help. I’m trying to add an iframe of a video hosted on Kolibri Studio in an HTML5 file, but when I publish it, I get the following message:

However, in Kolibri Studio’s preview mode, it works, and I can see the video.

Hi @Billy,

Do other HTML5 resources function correctly? The error message would seem to indicate some security policy has blocked the content from loading, which could happen for a number of reasons.

Could you share the HTML5 file via a direct message?

Regards,
Blaine
