PHP soap Could not connect to host

function getResult()
{
$url = "http://bcsz.xms.foxhis.com:8080/ItfServerWS/XmsWS?wsdl";//正式地址
// $url = "http://xms.foxhis.com:922/ItfServerWS/XmsWS?wsdl";//測試地址
$postjson = '{"param":{"begin":"2015-12-17","end":"2015-12-18","rmtype":"","ratecode":""},"hotelid":"G000001","pwd":"foxhis","cmmcode":"WEB","user":"foxhis","rq":"rminfo"}';

try {
    $client = new SoapClient($url, array("trace" => true, "connection_timeout" => 100));

// var_dump($client->__getTypes());//列出所有的功能
logE('傳入的json', $postjson);
$return = $client->getRoomAmount(array('arg0' => $postjson));//從接口地址獲得的數據
logE('接收的值', $return);
$result = $return->return;
logE('返回的json', $result);
return $result;
} catch (SOAPFault $e) {
print_r('Exception:' . $e);
return null;
}

}

用測試接口就能返回數據，但是用正式接口總是Could not connect to host異常，各位大神怎麼辦？
