XF 2.2 Stripe Payment Callback: "Request not validated (from unknown source)" (403 Forbidden)

Does anyone know why the Stripe payment callback would be failing with a "Request not validated (from unknown source)" 403 Forbidden server response?

All the various keys are correct and the charge succeeded. There's just no communication with my server. It just says, "Pending webhook response" in the Stripe payment activity log.
That message only happens in the PayPal handler, so I'm guessing you've set the webhook URL in Stripe incorrectly. I'm guessing it's missing the _xfProvider part of the URL. Check the Stripe payment profile page in the control panel for the currect URL (based on the board URL setting you have).
