We are using paypal IPN feature on our website but IPN request never reaches our server.
Paypal shows they have tried 16 times.
And gives this error
HTTP response code 403
Delivery status Failed
No. of retries 16
Checked apache log on server, it doesn’t show the request incoming. Cloudflare seems like a culprit.
Is there any log on cloudlfare I can check to see if the request is actually blocked by CF.
How to fix this?
