Stripe webhook poblems

Hey there,
I am getting an email by stripe about webhook problems. The connection to stripe looks actually good, and I am not sure why these problems appear. The email is all in german. I let it translate by google. Here it is:
“Hello,

There were problems submitting requests in live mode to a webhook endpoint associated with your E.?LMüHLE account. Stripe transmits webhook events to your server to alert you to events in your Stripe account, such as paid outs and new bills.

The URL of the failed webhook endpoint is: https://erlenbacheroelmuehle.de/wp-json/wc-stripe/v1/webhook

You (or someone on your team) have configured your Stripe account to deliver events to this URL. You can change your account’s webhook endpoints in the dashboard.

A failed webhook usually has no impact on your payments or payouts. However, please note the following:

If you use subscriptions, we need your webhook endpoint to notify you of new bills. These bills can be delayed up to three days if your endpoint is unable to receive them.

If you use Checkout and require the checkout.session.completed event as part of your purchase fulfillment process, you should review your completed payments. This way you can make sure that you have processed all past purchases.

We have attempted to deliver event notifications to the endpoint 224 times since April 9, 2022 at 03:35:57 UTC. If this endpoint is important to your application, you should try to fix the problem immediately. If you don’t need the webhook endpoint, you can delete it in your Stripe webhook settings. We will stop sending notifications to your webhook on April 18, 2022 at 03:35:57 UTC.

Here’s an overview of the errors we’ve had when trying to send webhook events:

224 requests had other errors while sending the webhook event.

In order for Stripe to acknowledge the transmission of the webhook event, you must return a status code between HTTP 200 and 299.

For more information about these errors and recent events in your account, see the events list and request logs on the dashboard.

Check out our documentation for more information on using webhooks.

Best regards

Your Stripe team”

Hope you can help me fixing this.
