It seems like Google returning the following error:
Google Maps JavaScript API error: RefererNotAllowedMapError
https://developers.google.com/maps/documentation/javascript/error-messages#referer-not-allowed-map-error
Can you check the referrer settings of your API key in the Cloud Console to see whether you have configured the correct one?
The current URL loading the Maps JavaScript API has not been added to the list of allowed referrers. Please check the referrer settings of your API key in the Cloud Console.
For example:
https://minersociety.com/*
*.minersociety.com*
*.minersociety.com/*
Do take note, after you save the new configuration setting, you might need to wait for a few minutes and then only retest for the new changes to your site.
