条带webhook在TEST模式下正确响应，但在LIVE下不

Question

有人可以帮我弄清楚为什么此条纹Webhook在测试模式下正确响应（通过给响应“ Worked！”），但是在实时模式下却没有响应！这是我的webhook端点：

<?php
require_once('../vendor/autoload.php');
// Set your secret key: remember to change this to your live secret key in production
// See your keys here: https://dashboard.stripe.com/account/apikeys
\Stripe\Stripe::setApiKey("####");

// You can find your endpoint's secret in your webhook settings
$endpoint_secret = '####';

$payload = @file_get_contents('php://input');
$sig_header = $_SERVER['HTTP_STRIPE_SIGNATURE'];
$event = null;

try {
  $event = \Stripe\Webhook::constructEvent(
    $payload, $sig_header, $endpoint_secret
  );
} catch(\UnexpectedValueException $e) {
  // Invalid payload
  http_response_code(400); // PHP 5.4 or greater
  exit();
} catch(\Stripe\Error\SignatureVerification $e) {
  // Invalid signature
  http_response_code(400); // PHP 5.4 or greater
  exit();
}

        // This function is leveraged to search through the JSON for specific values
        function searchArrayValueByKey(array $array, $search) {
            foreach (new RecursiveIteratorIterator(new RecursiveArrayIterator($array)) as $key => $value) {
                if ($search === $key)
                return $value;
            }
                return false;
            }
$input = @file_get_contents("php://input");         // this gets the POST data provided when the webhook pings this page
$event_json = json_decode($input, TRUE);            // decode the JSON, and TRUE turns it into a multidimensional array
$type = searchArrayValueByKey($event_json, 'type'); // Check the type of event sent from Stripe.com - example "charge.succeeded"
switch ($type) {                                    // depending on the event fired by Stripe, do something different.
        case "account.updated":
        echo 'Worked!';
        break;

    case "transfer.paid":
        echo 'Worked!';
        break;
    case "transfer.failed":
        echo 'Worked!';
        break;
    default:
        // An error has occured, this was not a Stripe.com event - log into your Stripe.com account and check the log.

}
http_response_code(200);
?>

在实时和测试之间切换时，我确保更改了我的秘密密钥和端点密钥。

我已经尝试了一切！甚至尝试联系条纹都无济于事，他们只是说他们无能为力。

任何对我做错事情的见解将不胜感激。
