C# HttpWebResponse上处理的奇怪对象异常

我正在开发一个程序，每5秒钟自动查询一个网站。在过去的几天里，它一直工作得很好，但今天当我重新启动它时，它一直在下面标记的行上抛出

System.ObjectDisposedException

。我应该提到的是，在同一台机器上通过浏览器访问此URL可以正常工作

代码：

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://www.bitstamp.net/api/ticker/");

request.Method = "GET";

try
{
    // ObjectDisposedException thrown here
    using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) 
    {
        using (StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8))
        {
            string resultString = reader.ReadToEnd();
            return resultString;
        }
    }
}
catch (WebException ex)
{
    // Handle it
}

System.ObjectDisposedException occurred
    _HResult=-2146232798
   _message=Cannot access a disposed object.
    HResult=-2146232798
    IsTransient=false
    Message=Cannot access a disposed object.

    ObjectName=SslStream

 InnerException: 

堆栈跟踪：

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://www.bitstamp.net/api/ticker/");

request.Method = "GET";

try
{
    // ObjectDisposedException thrown here
    using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) 
    {
        using (StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8))
        {
            string resultString = reader.ReadToEnd();
            return resultString;
        }
    }
}
catch (WebException ex)
{
    // Handle it
}

我做错什么了吗？在使用访问

之前，我甚至没有访问响应流，如何处理它

编辑：添加了url和堆栈跟踪
简化了一些事情，只需执行以下操作：

WebRequest.Create("https://www.bitstamp.net/api/ticker/").GetResponse();

我得到了WebException“服务器违反了协议。Section=ResponseHeader Detail=CR后面必须跟LF”，这表明服务器端出现了问题，解决这个问题的一个（可能是唯一的）方法是将以下内容添加到配置文件中：

<system.net> 
  <settings> 
    <httpWebRequest useUnsafeHeaderParsing="true" /> 
  </settings> 
</system.net>



不管怎样，这对我很有用。
堆栈跟踪是什么？网站是谁的？为堆栈跟踪和网站编辑如果你使用浏览器（从同一台机器）访问URL会发生什么情况？@stovroz URL在同一台机器上的浏览器中工作正常事实上，在另一台计算机上，我得到的是“服务器违反了协议”错误，而不是objectdisposed。很奇怪。
