cURL (6) guzzle error in Laravel 6

Thank you for the package, though I am getting an error:
```
Http\Client\Exception\NetworkException
cURL error 6: (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)
```

On looking at the above link it says could not resolve HOST. But my small php script is working fine. Please may you have a look at this issue
