PHP SoapClient调用.net -无法连接到主机

我有一个问题连接到。net web服务和WCF从PHP。当我从GoDaddy托管服务器(linux)运行PHP代码时，我收到以下错误:

SoapFault exception: [HTTP] Could not connect to host in /home/content/mydir/test.php:13 Stack trace: #0 [internal function]: SoapClient->__doRequest('__call('HelloWorld', Array) #2 /home/content/mydir/test.php(13): SoapClient->HelloWorld() #3 {main}

我能够成功地从我的Mac上的本地Apache服务器调用服务，使用相同的php代码和一个简单的。net客户端-两者都运行在不同的网络上，而不是web服务，所以我认为这不是绑定相关的问题。
WSDL本地保存在php服务器上。
我试图添加位置到PHP SoapClient.

在过去的一周里，我也在网上应用了许多其他的建议，但不幸的是。

我在这里使用的web服务是生成的HelloWorld web服务。wsdl中的wsdl定义部分:

        die();
        } catch(Exception $e) {
        die($e);
    }
?>

__getFunctions()和__getTypes()函数在任何地方都能正常工作。

谁有什么建议?

谢谢!: -)
