New Bug Encountered: Google rejects as unauthorized

I have workflows that generate email reports which display location coordinates as hyperlinks. The following is displayed when the hyperlink is clicked:
The Google Maps Platform server rejected your request. This IP, site or mobile application is not authorized to use this API key. Request received from IP address xxx.xxx.xx.xxx, with referer: https://mail.email.com/owa/?ver=15.0.1473.3&cver=15.0.1395.8&cf=1&vC=0
