Hi everyone,
Just a few days ago, once a day we started receiving emails with subject "PayPal Instant Payment Notification Warning" with the standard "Please check your server that handles PayPal Instant Payment Notifications (IPN). IPNs sent to the following URL(s) are failing:"... message.
However, the IPNs are *NOT* failing. I have checked the IPN logs, all looks OK and the same IPN URL has been working for 13 years or so now. In the IPN logs I could find a few retries here and then but nothing serious, and nothing in the past few days anyway. No failed messages etc.
The email is legit from PayPal. Has anyone else experienced this issue recently? Seems to be a bug on the PayPal side, will probably have to contact them. I also know PP were adding some new IPN IPs and asked via email to allow those new IPs in the firewall settings, so I have added those.
