Error processing checkout. Please try again. (create order not sent)

Hi,

since a while we can’t get customers to buy through Klarna, receiving “Error processing checkout. Please try again.” when clicking on order now. When checking the logs, Create session or Update session is sent, but no order is sent to the API.

Tried:
– deactivating all plugins related to payments / tax / shipping
– updating all plugins
– updating WP core
– deactivating the Confirm & Place Order Page (removing the one selected) in German Market plugin
– making sure “Force to use German Market Checkout Template” is deactivated in German Market plugin
– uninstall and reinstall the plugin
– creating new API keys

Still no success.
Looking at the logs in WC as well as Klarna site, I see the API sends a POST to /payments/merchant/<my_id>/v1/sessions with a correct response, and sends updates as well to /payments/merchant/<my_id>/v1/sessions/<correlation_token> with an empty response. However, nothing more happens…

See below for one order:

      "code":200
   },
   "timestamp":"2022-02-15 20:33:43",
   "plugin_version":"2.8.1"
}

This is the only call I can see in the log when I try placing an order. On the client side the error text mentioned above is displayed.

I literally tried everything that would come up to my mind – and other payments such as Paypal are working flawlessly.

Could you please help on that? I’m really blocked right now. I can give you access to the WordPress as well as to the JIRA with the whole description of steps and logs collected.

Thanks a lot in advance!
