Laravel Socialite Access Not Configured. Google+ API (truncated...) exception 'GuzzleHttp\Exception

Hi,

I am setting up Socialite2.0 on Laravel 5.3. I registered FB and Google apps and configured services.php with credentials.

Facebook login is working fine, but Google authentication fails at redirection. I found this in Laravel logs.

ERROR: exception 'GuzzleHttp\Exception\ClientException' with message 'Client error: `GET https://www.googleapis.com/plus/v1/people/me?prettyPrint=false` resulted in a `403 Forbidden` response:
{"error":{"errors":[{"domain":"usageLimits","reason":"accessNotConfigured","message":"Access Not Configured. Google+ API (truncated...)

How do I resolve this?
