Hi All, My ipn setup has worked for the past 10 years, nothing has changed, no ips are blocked. My customer software still receives the paypal IPN notices when a purchase is made. However, the response I send to PAYPAL (which is a valid paypal ipn response url) is no longer received or processed. So I get all those IPN warning messages and when for example a customer cancels a subscription, instead of getting one cancel message I get a dozen of them as paypal no longer receives my response messaging saying hey I got it. Something change in that area that I don't know about? I use PHP to send the response and it has worked for a very long time. What detail has changed that would cause this? Thank you!
