I have integrated Paypal in my Django(1.10) app using Django-paypal package. Everything works fine even payments processing perfectly well and I'm receiving IPNs from PayPal in Django admin. But PayPal send this email to me as:
Hello XXXXXXXXXX,
Please check your server that handles PayPal Instant Payment Notifications (IPN). IPNs sent to the following URL(s) are failing:
https://XXXXXXXXXX/paypal/ipn/
If you do not recognize this URL, you may be using a service provider that is using IPN on your behalf. Please contact your service provider with the above information. If this problem continues, IPNs may be disabled for your account.
Thank you for your prompt attention to this issue.
Thanks, PayPal
