REQUEST_DENIED error stops map display

My maps worked fine for many months but have all stopped loading. Here's a sample page: goldbeltbyway.com/index.php/map-guide/sh...road-interactive-map

I get this error: Directions service failed due to: REQUEST_DENIED

When I click ok I get: This page can't load Google Maps correctly.

I'm using: Component 10.0.1.0 Status Zh GoogleMap
Joomla! 3.9.10
PHP: 7.1.24

I do have a Google maps api and billing enabled.

Any help would be appreciated.
