Order sometimes failed – status code 0
-
Hi there,
i am encountering some problems with orders when users wants to pay with PayPal. I have already contacted support and PayPal, but there is no clue why or why I is happening. im struggling to find out or gather more information, what causes the problem.
Once in a while, maybe 1 or 2 orders paid with PayPal which are directly set to order status failed.
The most of the time paying with PayPal works perfect.
the log gives following information. this is not bound to exactly to one order, these are just a few log errors to help.
- SOMETIMES:
ERROR Cart simulation failed: Nonce konnte nicht überprüft werden. - ERROR Webhook verification failed.
- WARNING WC order ID was not found in webhook event
- This results sometimes in:
( [code] => 403 [message] => Forbidden ) Response Body: <?xml version="1.0" encoding="iso-8859-1"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>403 - Forbidden</title> </head> <body> <h1>403 - Forbidden</h1> </body> </html>
From what I can tell that sometimes costumer sees this fails two times on the websites but is then able fo finish the payment process with payan.
Reason, why Order is set to failed:
- WARNING [Fehler] Unbekannter Fehler bei dem Verbinden mit PayPal. Status code: 0.
- ERROR Payment failed: Die Zahlung konnte nicht verarbeitet werden. Bitte versuche es erneut oder kontaktiere den Shop-Administrator. [Fehler] Unbekannter Fehler bei dem Verbinden mit PayPal.

Hello @dawa2
Thanks for reaching out to us, we’re here to help.ERROR Cart simulation failed: Nonce konnte nicht überprüft werden.
This problem can arise due to the cart simulation feature in some environments. To address this, you can disable the cart simulation by adding the following Code snippet.
add_filter( 'woocommerce_paypal_payments_simulate_cart_enabled', '__return_false' );This should prevent the nonce verification issue from occurring.
ERROR Webhook verification failed.
WARNING WC order ID was not found in webhook eventThese issues are known to us, but currently, we do not have a definitive solution. I assigned this thread to a bug request for developers. As a workaround, we recommend reconnecting the plugin. You can do this by using the “Clear now” function in the Connection tab of the plugin settings. This action will establish a new connection with PayPal and may resolve these issues. Please monitor your logs after performing this action to see if the problem persists.

This is related to logging in with manual credentials and, in the current context, can be disregarded as it should not trigger any operational issues on your site.
