规格已满足,但仍然:未发送IPN,并且未验证握手。 请检查您的信息


I've been trying to integrate my website with the PayPal IPN, but I've been unsuccessful so far. The Paypal documentation HERE: SSL Certificate Upgrade Microsite entails some specifications that need be met. My server supports SHA-256 and uses VeriSign G2 Root Certificate as well. I've installed SSL on this domain too, but still I get nothing with the Paypal IPN.

I have a file IPNSampleCode.php at (NOT MY REAL WEBSITE) which is supposed to be called by the Instant Payment Notification (IPN) Simulator, but I keep getting 'IPN was not sent, and the handshake was not verified. Please review your information. ' whenever I run the IPN simulator against the IPN handler URL ''

What could I be missing, or what might I be doing wrong?

    Thank you for contacting PayPal Merchant Technical Services, I apologize for the delay in responding to your email.

    We are aware of this issue with our IPN Simulator and our development team is working on a fix. Until this issue is fixed, I'd suggest running your IPN tests by making payments in Sandbox as we do send IPN requests with every payment.

    If you have a similar issue with your payment tests, please let us know and we can take a look.

    My apologies for the inconvenience caused.
