I just spent a number of hours grappling with this. The correct answer is

"indeed to put the cacert.pem file and amend the php.ini file to match as suggested by Moez above. ..... but I kept on getting CURL error 60's The trick was getting a clean copy of the PEM file! Any method involving windows notepad or other editors corrupts the file and gives the cURL error 60 etc. Finally I found https://gist.github.com/VersatilityWerks/5719158/download and downloaded a tar file with a clean copy of the cacert.pem file ...... it then all worked perfectly."

And since you are working on Windows, this could be the problem.

While on local-host with Laravel you can easily bypass cURL error.

navigate to Client.php file (vendor\guzzlehttp\guzzle\src\Client.php)

Change "verify" to false

$defaults = [
        'allow_redirects' => RedirectMiddleware::$defaultSettings,
        'http_errors'     => true,
        'decode_content'  => true,
        'verify'          => false,
        'cookies'         => false
    ];

Windows : php.ini

and worked fine
