Stripe webhooks 的错误率为 92%，响应不可预测

Question

我是第一次设置 Stripe webhooks。我已经发出了数十次测试请求，错误率为 92%。失败发生的原因是不可预测的。

仪表板上的失败响应是：

Timed out connecting to remote host

或

Failed to connect to remote host

我的 webhook（我已将其简化以进行测试）。 8% 的情况下，我会收到带有 {received: true} 的 200 响应：

expressRouter.route('/hooks').post( async (req, res) => {

  const event = req.body;

  console.log("Event:");
  console.log(event);

  // Handle the event
  switch (event.type) {
    case 'payment_intent.succeeded':
      const paymentIntent = event.data.object;
      // Then define and call a method to handle the successful payment intent.
      // handlePaymentIntentSucceeded(paymentIntent);
      break;
    case 'payment_method.attached':
      const paymentMethod = event.data.object;
      // Then define and call a method to handle the successful attachment of a PaymentMethod.
      // handlePaymentMethodAttached(paymentMethod);
      break;
    // ... handle other event types
    default:
      console.log(`Unhandled event type ${event.type}`);
  }

  // Return a response to acknowledge receipt of the event
  res.json({received: true});
})

我已将 Stripe 的 IP 添加到 iptables。我在 Ubuntu 18.04 上使用 Caddy 运行我的服务器。非常感谢任何建议。
