I am building a dockerized (version 20.10.11) application with php7,nginx(1.21) images. I am adding colorbox jquery library for youtube popup.

Upon clicking youtube thumbnail link popup appears but videos not playing. In console errors appears like

Refused to frame 'http://myapp.docker.localhost:8000/' because an ancestor violates the following Content Security Policy directive: "frame-ancestors 'none'".

but it works without any issues in xampp,wamp etc.

How can I disable this restriction in docker?

I am pretty new to docker and nginx.
