Ionic external resource gives 404

I have in my app external images and youtube iframes, but both gives me 404 when I open threw my android phone (in the browser its good)

When I use the ios emulator its good, but when I use my android phone it fails.

Any ideas?

Not sure if this will solve your problem, but try installing cordova-whitelist-plugin:
