SoapFault exception: [HTTP] Error获取HTTP报头错误

一开始错误如下:

Fatal error: Uncaught SoapFault exception: [HTTP] error取回HTTP/var/www/me/public_html/soap.php:62栈跟踪:#0[内部函数]:SoapClient->__doRequest('http://dgpysws.... . net ''， 'urn:login'， 2,0) #1/var/www/me/public_html/soap.php (62): SoapClient -> __call("登录",/var/www/me/public_html/soap.php(62):SoapClient->login(Object(stdClass)) #3 {main}抛出/var/www/me/public_html/soap.php on line 62

我的代码工作完美，但几天前得到错误。

我在谷歌上尝试了所有的东西，所以那是:

1. ini set: ini_set('default_socket_timeout', 100);
2. SOAP初始化选项:'connection_timeout' => '100'
3. SOAP初始化选项:'keep_alive' => false
4. PHP版本5.4到5.6升级。

My tried codes:

$options = array(
        'trace'       => true,
        'exceptions'  => true,
        'keep_alive'  => false,
        'connection_timeout'  => 100,
        'soap_version' => SOAP_1_2
    );
$client = new SoapClient("http://dgpysws.epias.com.tr/dgpys/services/EVDServis.wsdl", $options);
$p1 = new stdCLass();
$p1->loginMessage = new stdCLass();
$p1->loginMessage->UserName = new stdCLass();
$p1->loginMessage->UserName->v = "USERNAME";
$p1->loginMessage->Password = new stdCLass();
$p1->loginMessage->Password->v = "PASSWORD";
$client->login($p1);

我可以得到所有类型:

$client->__getTypes(); // works

但是无法登录:

 $client->login($p1); // not works
