Good afternoon,
I need some technical support but this is the only forum I could find...
A client of ours received an email notification early this morning stating:
Please check your server that handles PayPal Instant Payment Notifications (IPN). Instant Payment Notifications sent to the following URL(s) are failing:
https://www.domain1.com/paypal/ipn
https://www.domain2.com/paypal/ipn
I took a look at the code handling these endpoints (Magento) and found that an exception is being thrown due to an empty response from the following endpoint:
https://www.paypal.com/cgi-bin/webscr
I set up a sandbox version of the same site and, while payments are being processed, I am still receiving an empty response from https://www.sandbox.paypal.com/cgi-bin/webscr
Because the response is empty, an exception is being thrown and the response header is being set to 503 Service Unavailable which is what I believe triggered the email our client received.
Is this an issue with Paypal?
