Php SoapFault:无法连接到主机

我用SOAP做了一个Web服务，是下一个吗

 $dataws=[
    'serie'=>$factura->serie,
    'folio'=>$factura->folio,
    'rfc'=>'xxxx123456',
    'key'=>'xxxx-xxxx-xxx-xxx-xxxxx'
    ];
    try {
    $url= 'https://portal3.xsa.com.mx/xsamanager/servicesb2b/CancelCFDIService?wsdl';              
    echo "<strong>url destino:<pre>";
    print_r ($url);
    echo "</pre></strong>";
        $client = new SoapClient(
            $url,
            array(
                'trace' => true,
                'exceptions' => true,
                'encoding' => 'UTF-8',
                'stream_context'=> stream_context_create(array('ssl'=> array(
                            'verify_peer'=>false,
                            'verify_peer_name'=>false, 
                            'allow_self_signed' => true //can fiddle with this one.
                                 )
                            )
                )
            )
        );
        echo "<strong>Funciones existentes</strong> <pre>";
        print_r ($client->__getFunctions());
        echo "</pre>";
        $response = $client->cancelaCFDI($dataws);

$dataws=[
“serie”=>$factura->serie，
“folio”=>$factura->folio，
“rfc”=>“xxxx123456”，
“密钥”=>“xxxx-xxxx-xxx-xxx-xxxxx”
];
试一试{
$url='1https://portal3.xsa.com.mx/xsamanager/servicesb2b/CancelCFDIService?wsdl';              
echo“url destino:”；
Whoops, looks like something went wrong.

打印（url）；
回声“”；
$client=新的SoapClient(
$url，
排列(
'trace'=>true，
“例外情况”=>true，
'编码'=>'UTF-8'，
'stream\u context'=>stream\u context\u创建（数组（'ssl'=>array(
“验证对等方”=>false，
'verify_peer_name'=>false，
'allow_self_signed'=>true//可以处理这个问题。
)
)
)
)
);
回声“存在的功能”；
打印（$client->uu getFunctions（））；
回声“；
$response=$client->cancelaCFDI（$dataws）；

调用函数$client->\uuu getFunctions（）时， 展示这个

现存功能 排列 ( [0]=>取消ACFDI响应取消ACFDI（取消ACFDI$参数） [1] =>mensajeResponse mensaje（mensaje$参数） )

显示函数，但调用函数$client->cancelaCFDI（$dataws）结果如下：

哎呀，好像出了什么事。 1/1 FacturasController.php第726行中的SoapFault： 无法连接到主机 实际上是一个控制器.php行726 在SoapClient->uu doRequest（'NUVEM7b6769894-fef7-4c1c-9d60-176de99377c4'，'http://10.10.10.41:8080/xsamanager/servicesb2b/CancelCFDIService/', '', '1', '0') 在SoapClient->\u调用（'cancelaCFDI'，array（array（'serie'=>'NUVEM'，'folio'=>'7'，'rfc'=>'NHI120830831'，'key'=>'b6769894-fef7-4c1c-9d60-176de99377c4'））实际上是在controller.php第726行 在SoapClient->cancelaCFDI（数组（'serie'=>'NUVEM'，'folio'=>'7'，'rfc'=>'NHI120830831'，'key'=>'b6769894-fef7-4c1c-9d60-176de99377c4'）中的FacturasController.php第726行 我使用php的SoapClient
