Oauth, Guzzle Post method

Hello,

I'm building a Lumen API with OAuth2 authentication, i followed this tutorial : http://esbenp.github.io/2015/05/26/lumen-web-api-oauth-2-authentication/ but i'm getting an error : "Fatal error: Maximum execution time of 60 seconds exceeded in C:\Users\user\Desktop\api\lumen\vendor\guzzlehttp\guzzle\src\Handler\CurlMultiHandler.php on line 99" Guzzle's post method ( and get method too) doesn't work for me

$app->get('api', function() use ($app){
    $client   = new \GuzzleHttp\Client();
    $response = $client->get('localhost:8000/api/hello');
    return $response;
});

$app->get('api/hello', function() use ($app){
    return "Hello";
});

It gives me the same errors By going in the apache logs i don't find anything, where can i find the lumen logs ? Thanks
