Exception: Unable to connect to remote server
实际错误：
Failed to invoke the service. Possible causes: The service is offline or inaccessible; the client-side configuration does not match
the proxy; the existing proxy is invalid. Refer to the stack trace for
more detail. You can try to recover by starting a new proxy,restoring
to default configuration,or refreshing the service.
错误详情：
The server was unable to process the request due to an internal error.
For more information about the error,either turn on
IncludeExceptionDetailInFaults (either from ServiceBehaviorAttribute
or from the configuration behavior) on the server in
order to send the exception information back to the client,or turn on
tracing as per the Microsoft .NET Framework SDK documentation and
inspect the server trace logs.Server stack trace: at

请注意,当Fiddler正在运行时,该服务正常工作.但是,如果我关闭Fiddler,则会显示异常：

根据以上Fiddler日志是我必须在web.config文件中更改以使其正常工作？
当从WCF测试客户端调用时.这是我试过的：
Web.config文件：
<?xml version="1.0"?>

</configuration>
以下是我在代码中的请求方式：
public class Service : IService
{
private string GetRestURL()
{
return System.Configuration.ConfigurationManager.AppSettings["resturl"];
}
private string GetUserName()
{
return System.Configuration.ConfigurationManager.AppSettings["MyUserName"];
}
private string GetPassword()
{
return System.Configuration.ConfigurationManager.AppSettings["MyPassword"];
}
public string method()
{
HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
// HttpClient
request.ContentType = "application/json; charset=UTF-8";
//request.ContentType = "text/xml; charset=UTF-8";
/*request.Headers.Add("X-Atlassian-Token","nocheck");
request.UseDefaultCredentials = true;
request.KeepAlive = true;*/
request.Method = method;
/*if (data != null)
{
using (StreamWriter writer = new StreamWriter(request.GetRequestStream(),Encoding.ASCII))
{
writer.Write(data);
}
}*/
string base64Credentials = GetEncodedCredentials();
request.Headers.Add("Authorization","Basic " + base64Credentials);
try
{
request.Headers.Add("Authorization","Basic " + base64Credentials);
response = request.GetResponse() as HttpWebResponse; //here its NULL
if (response.StatusCode != HttpStatusCode.OK)
{
throw new Exception(String.Format("Server error (HTTP {0}:{1}).",response.StatusCode,response.StatusDescription));
}
}
catch (Exception ex) //Here I'm getting exception
{
throw new Exception(ex.Message);
}
}
这是我的方法签名：
[ServiceContract]
public interface IService
{
[OperationContract]
List<ProjectDescription> GetProjects();
}
这是通过调用WCF测试客户端调试时得到的内部异常：
这是我内心的异常
A connection attempt Failed because the connected party did not properly respond after a period of time,or established connection Failed because connected host has Failed to respond 165.254.xxx.xxx:443
注意：当我从控制台应用程序进行调试时,没有调试异常.正如我所说,控制台应用程序正常工作,我可以从服务返回结果.
更新：当我在控制台应用程序中添加这个服务作为“添加引用”时,它的工作正常.但是,当我在同一个控制台应用程序中添加为“添加服务引用”时,它显示同样的错误.我的网络是阻止某些东西吗？请帮忙.
如何纠正？还有什么我需要添加到web.config中吗？或者我需要允许URL作为受信任的URL吗？
