Google Api Oath Exception Issues
<p>I am newer to the Google Plus Api, but I have followed each and every rule to integrate G-Plus API in my WEB. But every time I get stuck at the issue:</p>

<pre><code>Fatal error: Uncaught exception 'apiAuthException' with message 'Error refreshing the OAuth2 token, message: ''' in C:\AppServ\www\googleplus-source\google-api-php-client\src\auth\apiOAuth2.php:203

</code></pre>

<p>What could be the reason for this error?</p>
