App payment, PHP background integration

I downloaded the 2.0 server SDK. After passing the parameters to the client, the client kept prompting that the system is busy. Please try again later. I don’t know where the problem is. Is it a problem with the background or the client?

    This is possible for you, please check the parameters carefully according to the documentation. Pay special attention to check whether the certificate is correct
