Webhook creating error
Hi,I am trying to create a new webhook.
I followed the guide https://developers.ringcentral.com/guide/notifications/webhooks/quick-start#php
After starting ngrow and starting the php file I get this error
PHP Fatal error: Uncaught GuzzleHttpExceptionRequestException: cURL error 3: (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for /restapi/oauth/token in /var/www/vendor/guzzlehttp/guzzle/src/Handler/CurlFactory.php:211
