Users of the site try to checkout via PayPal. After providing PayPal with the valid payment details they get redirected back to the checkout page and the order has not been completed.
Unfortunately, it is not every time on every order. Sometimes the orders go through just fine. We have, however replicated it on our end and do not see where the problem is.
In the server logs, the user gets redirected back to /store/checkout/confirm/?token= with a PayPal token. They do not see the order-status page with the payment details.
Along with the token from PayPal, there is a PayerID= included in the URL in the server logs. That is followed by a GET /?sccss=1&ver=4.5.3
