Google API manager

Creating an API for a Reverse Geocoding With Google Map API And PHP!

After created an API key, when I trying to test it, I have received the next message:
https://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&key=AIzaSyDWpVDQyIieftj5WOKekltjoDx3z8rnowY

Result:

{
“error_message” : “This IP, site or mobile application is not authorized to use this API key. Request received from IP address 86.182.65.135, with empty referer”,
“results” : [],
“status” : “REQUEST_DENIED”
}

Once I click to save, I have received the next message:

Sorry, there’s a problem. If you have entered information, check it and try again.
Otherwise, the problem might clear up on its own, so check back later.
