Error stripe WebHook

I setup the weebhook, like in documentation:

https://adoptahost.com/?wc-api=wc_stripe

and stripe send me a mail that there is an error with the weebhook 100% Fail.

Maybe it is important to know that i do not have any subrsciptions plans, a vendor register for free always.

Thanks a lot, any idea how to solve?

Here the mail i got:

Hi there,

We’re contacting you because we’re still having trouble delivering data to a webhook endpoint associated with your AdoptaHost.com account in live mode. Webhooks are used to notify your server about events that happen in your Stripe account, such as a payout completing or an invoice being created. The failing webhook endpoint is https://adoptahost.com/?wc-api=wc_stripe.

You or someone on your team has added that endpoint in your Stripe webhook settings, which you can view and edit here: https://dashboard.stripe.com/account/webhooks.

Please note that in most cases a failing webhook does not impact your payments or payouts. However, if you use subscriptions we rely on your webhook endpoint to notify you of new invoices. These invoices may be delayed for up to three days if your webhook is unable to successfully receive them. If you use Checkout, you may be handling the checkout.session.completed event as part of your purchase fulfillment process as described here: https://stripe.com/docs/payments/checkout/fulfillment#webhooks. If you do, failure to handle these events may interfere with purchase fulfillment.

We’ve attempted to notify the endpoint 70 times since April 30, 2020 at 04:40PM. If this endpoint is important to your application, please try and fix the issue. If you do not need the webhook endpoint you can delete it from your Stripe webhook settings. We will stop sending notifications to your webhook by May 9, 2020 around 04:40PM.

Here is the summary of errors we have received when sending you webhooks:
* 69 requests had other errors while sending the webhook.
* 1 request timed out, make sure your server is able to respond fast enough and that you do as much work asynchronously as possible.

You need to return anything between a HTTP 200 to 299 for the webhook to be considered successfully delivered.
For more details on the errors, you can find your events page here: https://dashboard.stripe.com/events.

You can also always review the history of webhooks and failed request logs right from your dashboard: https://dashboard.stripe.com/events.

This email is the last time we’ll reach out to you before disabling the webhook.

For more in depth information about how to use webhooks, we recommend taking a look at our documentation: https://stripe.com/docs/webhooks.

Yours,

The Stripe team
