How to add a damn iframe to a site without errors?

Question

Nginx

There is a site site.ru.
There is another site where I take the video from - remotesite.ru .

So when I add a video to my site, I get an error:

Blocked a frame with origin " remotesite.ru " from accessing a frame with origin " site.ru ". Protocols, domains, and ports must match.

Registered Content Security Policy in NGINX. Prescribed Content Security Policy in HTML. I wrote Content Security Policy in a fucking RoR project in ApplicationController.

Nothing helps. I'm already boiling and about to burst.

Help me please.

PS Yes, yes. This is my third theme of the night, but it's also different. I will refine the information. Moderators please don't delete :(

Answer 1

it's not so easy
, find an example that works, and sniff what's where,
well, you'll have to put something in the root of the domain
