Paypal IPN现在返回无效- PHP代码以前工作正常

我使用下面的类来处理IPN数据:https://github.com/WadeShuler/PHP-PayPal-IPN(它已经工作很长时间了)

最后一次成功处理的付款是在9月28日，下一个IPN付款是在10月5日，返回了一个无效的响应，从那以后每次付款都是无效的。

如果我在IPN模拟器中测试，消息处理成功。沙箱或活动，响应无效。我本以为沙盒会有一个设施，我可以审查为什么一个消息被拒绝为无效，但这似乎不是情况?这当然是看到拒绝原因的简单方法，我错过了什么吗?

从Paypal传回的数据是:

我发送回Paypal的响应是:

在payback-test.php中的代码是:

<?php
  include_once("f_common.php");
  include_once("IpnListener.php");
  use wadeshuler'paypalipn'IpnListener;
  $listener = new IpnListener();
  $listener->use_sandbox = true;
  $dbh = open_db();
  $res = 'UNKNOWN';
  try {
    $listener->requirePostMethod();
    $verified = $listener->processIpn();
  } catch (Exception $e) {
    error_log($e->getMessage());
    exit(0);
  }

  if ($verified) {
      $res = "VERIFIED";
  } else {
      $res = "INVALID";
    }
  $stmt_debug = $dbh->prepare('INSERT INTO fyd_paypal_ipn (post_data, response_data, status, message_time) VALUES (:post_data, :response_data, :status, UTC_TIMESTAMP())');
  $stmt_debug->execute(array(':post_data' => $listener->rawPostData, ':response_data' => $listener->debug_response, ':status' => $res));
?>

请注意，为了本练习的目的，我还修改了IpnListener类，以便我可以获得响应的副本以用于调试。

在文件顶部的变量声明中，我将$rawPostData设为公共，并添加了这个变量:

public $debug_response;

并在使用它之前存储它的值:

        $this->debug_response = $req;
        if ($this->use_curl) {
            $res = $this->curlPost($req);
        } else {
            $res = $this->fsockPost($req);
        }

我假设贝宝方面发生了一些变化，首先阻止这种工作，但我看不出它是什么，特别是因为我的反应似乎是正确的(相同)，我在沙盒方面找不到任何东西，帮助我确定为什么它被视为无效?不幸的是，我在底部跟踪IPN帖子数据和响应的调试代码是新的，所以我没有较旧的(工作的!)消息集来比较内容。
