PayPal is telling me that the IPNs are not being received correctly for payment transactions. It seems odd because NONE of the transactions in PayPal's "IPN History" that are the payment type go through. They are all marked as a 500 response code and "retrying".

But ALL transaction types of other types (such as refund) are giving the HTTP 200 response and are marked as "sent".

And finally, even though the "IPN History" shows all payment transactions as 500 codes, all the corresponding orders have been added to my DB correctly.

Any idea what the issue could be?
