PayPal IPN Issue

Filed under: Development

This morning I got an email saying a purchase (on this site) hadn’t been confirmed via the paypal IPN, and was forever “waiting to receive confirmation from the payment processor”. Initially I thought it must have been a one-off, but have since received several more reports of the same issue.

After a bit of searching, I found the following comment by a paypal developer:

Apologies for any inconvenience this issue with IPN may have caused you. We are aware of the issue and working it as high priority, to get it resolved as soon as possible.

As a workaround, if you use port 443, rather than port 80, IPN will work.

Once resolved, we will update any threads created for this issue, so that everyone is aware. Thanks for your continued patience!

I therefore did as suggested and added the option to use port 443 (if the server supports it) instead of port 80, which did indeed fix the problem. I’ve also added the same code to the OIO paypal module, since port 443 seems to be the recommended default now.

There’s no urgent need to upgrade, unless this problem persists for a while.

So, if you’re experiencing any problems with paypal IPNs today, now you know why!
