Help with stripe webhooks

Hi, We need some help resolving a few issues with Stripe in our system. We are using gravity forms and we receive this from stripe: Hi there, We’re contacting you because we’re still having trouble delivering data to a webhook endpoint associated with your account in live mode. Webhooks are used to notify your server about events that happen in your Stripe account, such as a transfer completing or an invoice being created. The failing webhook endpoint is [login to view URL] You or someone on your team has added that endpoint in your Stripe webhook settings, which you can view and edit here: [login to view URL] Please note that in most cases a failing webhook does not impact your charges or transfers. 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. We’ve attempted to notify the endpoint 1008 times since October 17 at 12:36PM. 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 December 09. This email is the last time we'll reach out to you before disabling the webhook. One recent call to your endpoint returned an HTTP status code 301, with a redirect to [login to view URL] If you intended to have notifications sent to that URL, you may just want to update your webhook URL to [login to view URL] You can view the event for this failed notification here: [login to view URL] To acknowledge receipt of a webhook, your endpoint should return a 2xx HTTP status code. For more in depth information about how to use webhooks, we recommend taking a look at our documentation: [login to view URL] Yours, The Stripe Team
