Situacija je sljedeća, na web siteu je implementirano plaćanje putem Paypala pomoću IPN-a, transakcije su uredno prolazile (njih desetak zasada) ali nakon par dana na mail sam dobio sljedeću poruku od Paypala:
Please check your server that handles PayPal Instant Payment Notifications (IPN). IPNs sent to the following URL(s) are failing:
//url...
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.
Razlog?
