Paypal付款 - 500错误

Question

I am trying to make a automatic payment in my system, and got it to work perfectly in sandbox mode. As soon, as I switch to live mode I am receiving a 500 error. I am not sure if maybe the URL's I've copied are maybe from a legacy site or something.

Here is my params:

My post back error looks like:

{"ClassName":"PayPal.Exception.HttpException","Message":"The remote server returned an error: (500) Internal Server Error.","Data":null,"InnerException":null,"HelpURL":null,"StackTraceString":" at PayPal.HttpConnection.Execute(String payLoad, HttpWebRequest httpRequest)\r\n at PayPal.APIService.MakeRequestUsing(IAPICallPreHandler apiCallHandler)\r\n at PayPal.BasePayPalService.Call(IAPICallPreHandler apiCallHandler)\r\n at PayPal.AdaptivePayments.AdaptivePaymentsService.Pay(PayRequest payRequest, String apiUserName)\r\n at Cashbackeroo.Payment.PayPal.PayPalPaymentService.Pay(PaymentRequest paymentRequest)","RemoteStackTraceString":null,"RemoteStackIndex":0,"ExceptionMethod":"8\nExecute\nPayPalCoreSDK, Version=1.7.1.0, Culture=neutral, PublicKeyToken=5b4afc1ccaef40fb\nPayPal.HttpConnection\nSystem.String Execute(System.String, System.Net.HttpWebRequest)","HResult":-2146233088,"Source":"PayPalCoreSDK","WatsonBuckets":null}

Try to open the Paypal URL dirrectly in your browser. Does it returns a 500 server error or 200 ok?

Usually when the Paypal servers are down, the response is 500 server error.
