Google Maps API error

Hello

It is quite complicate with API (embed or javascript?) but I guess I have done it correctly but get an error, Map couldn’t be loaded and I should look in java script console:

I see there:

Google Maps JavaScript API error: RefererNotAllowedMapError
https://developers.google.com/maps/documentation/javascript/error-messages#referer-not-allowed-map-error

Did I something wrong?
