无法从传输连接中读取数据:一个现有的连接被远程主机强制关闭

在我开始之前

首先让我提前道歉，如果这是一个重复的问题，因为似乎有几个问题与"现有连接被远程主机强制关闭"有关，但是我似乎无法从这些其他问题中获得任何帮助，因为它们同样与FTP(不是HTTP)有关，似乎是由于请求长度问题，或者我根本不理解答案。

我试图使用System.Net.WebRequest使第三方服务的REST API调用移动应用程序推送服务Parse.com。尽管这个请求在95%的情况下都能正常工作，但它会间歇性地抛出System.Net.Web异常。

我读过的一些类似的帖子表明，这可能与发送请求的大小有关，但是这似乎不太可能，因为每次请求的大小大致相同(注意:这可能是一个无知的假设)。

这是我用来制作Web请求的方法

public static WebResponse SendPushHttpRequest(
            string payload, string apiID, string apiKey)
    {
        WebRequest request = WebRequest.Create("https://some.api.com/1/endpoint");
        request.ContentType = "application/json";
        request.Method = "POST";
        request.Headers["Application-Id"] = apiID;
        request.Headers["API-Key"] = apiKey;
        byte[] buffer =
            System.Text.Encoding.GetEncoding("UTF-8").GetBytes(payload);
        //string result = Convert.ToBase64String(buffer);
        Stream reqstr = request.GetRequestStream();
        reqstr.Write(buffer, 0, buffer.Length);
        reqstr.Close();
        try
        {
            using (WebResponse response = request.GetResponse())
            {
                return response;
            }
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }

这是抛出的System.Net.Web异常底层连接已关闭:在接收时发生意外错误。

内部异常无法从传输连接读取数据:远程主机强制关闭了现有连接。"}系统。SystemException {System.IO.IOException}

异常状态ReceiveFailure

堆栈跟踪

Web服务器响应

 GenericParameterAttributes '(((System.Reflection.RuntimeMethodInfo)(((System.Exception)(ex)).TargetSite)).ReturnType).GenericParameterAttributes' 

抛出类型为"System"的异常。System. reflection . genericparameterattributes {System. reflection . genericparameterattributes}InvalidOperationException}

消息:"方法只能在一个类型上被调用。string

最后但并非最不重要的原始HTTP请求

如果有人能帮我解释一下这个问题，我将不胜感激。
