PHP Fatal error: Uncaught GuzzleHttp\Exception\RequestException: cURL error 2: (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) in numerous libraries that require guzzle

I am still getting this while using 2 packages (Packagist libraries) from different developers that have guzzle as a dependency.

I am getting this using the Following:

Any help would be greatly appreciated.

I have able to replicate this several times and I am getting the same result.
I started a new project guzzle-test and installed guzzle using:
composer require guzzlehttp/guzzle:^7.0

I created index.php and added the following simple code:
`<?php
require 'vendor/autoload.php';

use GuzzleHttp\Client;

$client = new GuzzleHttp\Client(['base_uri' => 'https://api.nitrado.net/']);
$response = $client->request('GET', 'ping');

die("

".print_r($response, true)."

");`

which is supposed to return
HTTP/1.1 200 OK { "status": "success", "message": "All systems operate as expected." }

however I get a failure, here is the stack trace:

Any ideas?

I seem to be getting this on my mac. When I try from a remote hosting provider it seems to work. Keep getting the same error when working locally
