8. Error messages
Here are some potential error messages and how you can deal with them.
"You must use an API key to authenticate each request to Google Maps Platform APIs"
This means that the APIs has not been completed. Check if you completed all the above points and if something is missing.
"This page can't load Google Maps correctly"
Please make sure that Google billing profile is enabled in your Google account and the Browser Key restrictions are set up correctly as per above guide. Once this is done, please try again.
"This IP, site or mobile application is not authorized to use this API key. Request received from IP address X.X.X.X, with empty referer"
This might happen when Google API Server Key restrictions are enabled, but the IP address (X.X.X.X) displayed in the error message is not added to allowed IP addresses list.
Sometimes your server might be using few IP addresses to connect to Google API service in the background therefore you will need to list all of these IPs in your Google account.
To add missing IPs please go to your Google API Console and edit Server Key and then in “Application restrictions -> IP addresses (web servers, cron jobs, etc.) -> Accept requests from these server IP addresses” section add the IP address displayed in error message (X.X.X.X).
