.net 基础连接已经关闭 连接被意外关闭 怎么搞

我通过网络去获取信息，在一台server 08上工作完全正常，另一台老这样“基础连接已经关闭 连接被意外关闭”。有时候会正常，但我也不知道为什么。
String url = APPLICATION_TOKEN_URL;
ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback((s, c1, c2, e) => true);
HttpWebRequest hwr = WebRequest.Create(url) as HttpWebRequest;
hwr.ProtocolVersion = HttpVersion.Version10;
hwr.Method = "POST";
hwr.ContentType = "application/x-www-form-urlencoded";
hwr.Headers.Add("Authorization: Basic " + APPLICATION_AUTH);
string postdata = "grant_type=client_credentials";
byte[] data = Encoding.UTF8.GetBytes(postdata);
using (Stream stream = hwr.GetRequestStream())
{
stream.Write(data, 0, data.Length);
}
var result = hwr.GetResponse() as HttpWebResponse;

异常就出在最后一句上：基础连接已经关闭 连接被意外关闭

Answer 1

把HttpWebRequest 的Timeout 时间设置的长一点
