cURL不在服务器上工作，但在本地主机上工作

我正在laravel上的一个小网站上工作，我从webservices中检索了一些数据，并在我的本地主机上使用它，一切都很好，然后我将它上传到我的服务器上，所有这些都不能发送请求。

服务器1 = http://testing2.vire-news.com/(host: godaddy)

server 2 = http://testing.asmani.pk/(host: hostgator)

如果你点击搜索，它不会给你webservice的结果。

我已经在stackoverflow上搜索了所有的CURLOPT_POST, CURLOPT_FOLLOWLOCATION等，没有任何结果

在Server 1上给出错误

"连接emexonline.com端口3000失败:连接被拒绝"

在Server 2上，

保持连接，然后超时。我做了一个简单的php文件相同的代码测试出laravel环境，它也不工作。

注意:我已经测试了其他curl网络服务，如facebook和twitter的api，他们都在这些服务器上工作得很好，我已经联系了网络服务提供商，他们说他们这边一切都很好，其他客户也在使用他们的网络服务，没有任何问题。

下面是我从XML数据中获取用户名和密码的代码。在本地主机和服务器上一切正常，它给出错误，所有其他功能工作正常，只有webservice没有连接。

        $headers = array(

        "SOAPAction: '"http://dpd.com/common/service/LoginService/2.0/getAuth'"",

        );
        $url = 'http://emexonline.com:3000/MaximaWS/Service.asmx';
        $curll = curl_init();
        curl_setopt($curll, CURLOPT_URL,$url);
        curl_setopt($curll, CURLOPT_RETURNTRANSFER,1);
        curl_setopt($curll, CURLOPT_TIMEOUT, 30);
        curl_setopt($curll, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($curll, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($curll, CURLOPT_POSTFIELDS, $xml_data);
        $reply = curl_exec($curll);

别问我怎么用curl_errno($ch)、curl_error($ch)和curl_getinfo($ch)了，我已经用过了，结果也出来了。
