Solution 1:

From the picture you posted, it say it's disabled...

Go to the Developer Console

Navigate to Google Maps -> APIs

Search for Geocoding and click on Google Maps Geocoding API -> Enable API. Do the same thing for Geolocating

If you are using get method to fetch the places, you need to enable

Google Places API Web Service

I was facing the same issue and resolved after enabling it.

EDIT: According to https://developers.google.com/places/web-service/get-api-key

Note: The Google Places API Web Service does not work with an Android or iOS restricted API key.

So you have to create new key if or remove restricted access of existing key to work it properly.
