False positive Embed (Basic) API

[pdelteil]

I used the latest version (pulled the code one hour ago)

Try this key AIzaSyB3MeUSpCntta2BW8UeLmVlRgnM7tB6hio.

Then if you try the generated iframe code:

<iframe width="600" height="450" frameborder="0" style="border:0" src="https://www.google.com/maps/embed/v1/place?q=Seattle&key=AIzaSyB3MeUSpCntta2BW8UeLmVlRgnM7tB6hio" allowfullscreen></iframe>

You will get this:

I am saving the iframe code as html file on my local pc and opening it in the browser which successfully loads the iframe.
On your case, since you loaded iframe to www.w3schools.com, probably it is returning error.
Adding <meta name="referrer" content="no-referrer"/> to your HTML code will bypass that control & solve the issue.
