Map not displayed on website

I get the map displayed normally in the WP backend when i edit listings.
But not in the view for users on the website, however.
I had the problem with when I used Open Streets, I thought I could solve the problem using Google Maps.
I got a new API from Google and also deposited the payment data. All rights released without restrictions.
The API key deposited at GD.
However, the circle for loading the page is still displayed on the page.

When I enter a location for “Get Directions” there is an error message “Address not found”

What am I doing wrong? Do I still have to give GD rights to let a non-registered user see the map?
What can i do? Any suggestions?
