Paypal Ipn Notification Error Rate Topic   - - - - -

 

Posted 28 October 2015 - 08:19 PM #1

PayPal seems to work properly.  Anybody have an idea why we receive the following error?

 

From: service@paypal.com [mailto:service@paypal.com]
Sent: Tuesday, October 27, 2015 10:05 PM
To: John Doe
Subject: PayPal Instant Payment Notification Warning

Hello John Doe,

Please check your server that handles PayPal Instant Payment Notifications
(IPN). IPNs sent to the following URL(s) are failing:

 

https :// mywebsiteiscool.com/index.php?dispatch=payment_notification.return&payment=paypal

 

If you do not recognize this URL, you may be using a service provider that
is using IPN on your behalf. Please contact your service provider with the
above information. If this problem continues, IPNs may be disabled for your
account.

Thank you for your prompt attention to this issue.

Thanks,
PayPal


Pro Computer

Can you ask them specifically what they are seeing as a response to indicate that it's failing?

Are there any errors in your PHP error_log file?

What are the order statuses related to those failed IPN notifications?

What does the payment area of the order.details show as "Reason text"?

What version of cs-cart are you running.  I don't think any version of Paypal for V4 before 4.3.4 is viable.

Something wrong with the access. I see default wordpress page through the mentioned URL:

 

http://prntscr.com/8wlc1e

 

It means that the IPN is not processed by CS-Cart

I would search your Apache access logs for instances of dispatch=payment_notification.return and see if you have some successes or whether it's all failures.  If all failures, then I'd assume you have an ownership/permissions issue on your site. But the access logs will probably give you more detail.

 

The dispatch=payment_notification.return should define('PAYMENT_NOTIFICATION', true) and then call app/addons/paypal/payments/paypal.php.  So odds are that it is the reference to paypal.php that is actually generating the 404.  Check .htacess as well as ownership/permissions of all directories/files in the path.

Please also make sure that the .htaccess file exists in the app/addons/paypal/payments directory

Hi

 

I have the same issue, while everything was working fine, about 4 days ago all successful orders started coming in as "open" I am running CS Cart Version 4.3.3

 

IPNs sent to the following URL(s) are failing: 

https://www.greennbr...tion.paypal_ipn 

 

When I check with the hosting provider, below is their response ---

 

It appears the command PayPal provides is OS specific. The one provided uses cert directory locations for possibly an Ubuntu system where your VPS is running CentOS. When omitting the " -CApath" option the command executed successfully and returned an OK:

--

This shows it's not a server configuration or an SSL certificates. This leaves be to believe it maybe an issue with CS-Cart and the way the URL's are provided causing the redirect issue when PayPal attempt to connect. 

 

Without omitting the "-CAPath" option the results were
