IPNs are retrying and failing

[SpottySpoon]

Hello,

I have received an email from PayPal, indicating that "IPNs sent to the following URL(s) are failing.."

The website IPN has been fairly stable for the last year.

Checking the IPN history, it looks like PayPal is actually sending the IPNs to the wrong URL protocol.

The URL that has been designated as the IPN handler, begins with 'http://www'

However PayPal is attempting to send the majority of the IPNs to 'http:/www'

You'll notice the missing forward slash. This looks to be the issue.

How can I resolve this?

thanks
Michael.

I'm experiencing many IPN callbacks for the same transaction and some of them fail to verify.

PayPal is making some maintenance this days, I hope they will fix the issue on their side soon.

BTW. They suggest to use HTTP/1.1 protocol instead of the HTTP/1.0 in our scripts.

I'm having the same problem, starting around about a month ago.

The IPN URL is missing the forward slash, but *not* all of the time.  Probably 75% of the time.

Did you ever find a resolution for this?

I have been seeing the same problem--some IPNs being sent to http:/... instead of http://... .  Does anyone have a resolution to this?

I contacted PayPal and no feedback yet.

Solution found for me

maybe this will help others

In your current method the website is sending the information over in a GET not a POST. For some reason when information is sent over as a GET we will process the transaction, but it cuts out a '/' from the return and IPN URLs.

if you see below this is a capture I created by going through checkout:

The first part (https://www.paypal.com/cgi-bin/webscr&page_style=velvet) should have the '&' changed to a '?'. If you change that, the information will be sent as a POST, which it should be and the issue will go away.

If you are using personalized pages in paypal...pay atention to this
