PHP ios推送nofitcation错误:stream_socket_client():SSL操作失败,代码为1

Question

我已经阅读了关于这个问题的所有其他帖子,但仍无济于事.

我知道这个问题可能会出现错误的证书,但是在我将证书和密钥合并到我放在服务器上的单个.pem文件之前,我验证了它的证书和密钥都是有效的.

我完全不知道如何解决这个问题,所以我们非常感谢所有建议.这是我的服务器代码

$ctx = stream_context_create();
        stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem');
        stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);

        // Open a connection to the APNS server
        $fp = stream_socket_client('ssl://gateway.sandbox.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);

PS ck.pem文件与读取权限设置在同一目录中.

这是完整的错误消息:

Warning: stream_socket_client(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed in /var/www/site/pages/Callback.php on line 3515 Warning: stream_socket_client(): Failed to enable crypto in /var/www/site/pages/Callback.php on line 3515 Warning: stream_socket_client(): unable to connect to ssl://gateway.sandbox.push.apple.com:2195 (Unknown error) in /var/www/site/pages/Callback.php on line 3515 Failed to connect BECUSE OF ERROR: 0
UPDATE
It does seem to be a certificate validation issue after all but Im not sure why, when I check the ssl against APNS I get this error:
