We recently migrated our entire server (our account & about a hundred others) to a new host & we received an email from PayPal yesterday that our IPN Notifications are failing & we're in danger of having IPN's switched off.
I checked our orders & there are no pending payment statuses as I would expect if IPN's were truly failing
all store settings are correct
our IPN settings within PayPal are correct
no URLs changed with the migration
IPN Simulator returned: "IPN was sent and the handshake was verified."
Has anyone had this issue previously & what might we be overlooking?
Check the IPN history section of your account to check the status of recent IPN transmissions. IPN's which have issues will show a status of "retrying" or "failed". Click on the "message id" to view specific details about the IPN message, such as the response status and number of delivery attempts.
Was my post helpful? If so, please give me a kudos!
