Issues with Google Maps API calls and caching plugins

Hello!

We are using WP Store Locator on our site and also make use of caching plugins Comet Cache Pro and Fast Velocity Minify. We face a 403 error every 3 days while trying to load https://maps.googleapis.com/maps/api/js/AuthenticationService.Authenticate – we already added googleapis.com to the ignore list of those two plugins but still facing this issue.

Is there any best-practice on how to use WP Store Locator together with caching plugins?

Thank you and best regards,
Christian
