Guzzle6 can't resolve external websites while in local environment - laravel

Question

I am having trouble using Guzzle with external websites when I'm in my local, development environment. I am able to use Guzzle without incident with other local sites on my machine.
I am currently unable to use Guzzle with external websites in my local environment.
The Code
I have the following test route in my local Laravel application:
Route::get('guzzle', function() {
$client = new GuzzleHttp\Client();
$response = $client->get("http://www.google.com");
dd($response);
});
The Response
When I execute this code from my local environment I receive the following error:
cURL error 6: Couldn't resolve host 'www.google.com' (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)
I am able to use Guzzle with local sites.
The Code
Route::get('guzzle', function() {
$client = new GuzzleHttp\Client();
$response = $client->get("http://test.dev");
dd($response);
});
The Response
Response {#180 ▼
-reasonPhrase: "OK"
-statusCode: 200
-headers: array:7 [▶]
-headerLines: array:7 [▶]
-protocol: "1.1"
-stream: Stream {#171 ▶}
}
...I need help.
I've looked at this for so long, I need some fresh ideas. Hopefully someone has an idea or a starting point.
This is the full error message that Laravel returns.
