Twitter API 不支持证书密钥算法

我们正在从 Twitter 时间线中提取最新的推文，但我看到一个错误"不支持证书密钥算法"，并显示一条消息"基础连接已关闭：接收时发生意外错误。这只发生在舞台和实时服务器上，而不是在我的开发机器上。

该页返回标准服务器错误。我们用网名调用的类如下。我们已经仔细检查了 oAuth 使用者密钥和机密是否正确。

public static List<Tweet> GetTimeline(string screenName)
{
    try
    {
        // Do the Authenticate
        var authHeaderFormat = "Basic {0}";
        var authHeader = string.Format(authHeaderFormat,
                                           Convert.ToBase64String(Encoding.UTF8.GetBytes(Uri.EscapeDataString(oAuthConsumerKey) + ":" + Uri.EscapeDataString((oAuthConsumerSecret)))
                                               ));
        var postBody = "grant_type=client_credentials";
        HttpWebRequest authRequest = (HttpWebRequest)WebRequest.Create(oAuthUrl);
        authRequest.Headers.Add("Authorization", authHeader);
        authRequest.Method = "POST";
        authRequest.ContentType = "application/x-www-form-urlencoded;charset=UTF-8";
        authRequest.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
        using (Stream stream = authRequest.GetRequestStream())
        {
            byte[] content = ASCIIEncoding.ASCII.GetBytes(postBody);
            stream.Write(content, 0, content.Length);
        }
        authRequest.Headers.Add("Accept-Encoding", "gzip");
        WebResponse authResponse = authRequest.GetResponse();
        // deserialize into an object
        TwitAuthenticateResponse twitAuthResponse;
        using (authResponse)
        {
            using (var reader = new StreamReader(authResponse.GetResponseStream()))
            {
                JavaScriptSerializer js = new JavaScriptSerializer();
                var objectText = reader.ReadToEnd();
                twitAuthResponse = JsonConvert.DeserializeObject<TwitAuthenticateResponse>(objectText);
            }
        }
        // Do the timeline
        var timelineFormat =
                "https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name={0}&include_rts=1&exclude_replies=1&count=20";
        var timelineUrl = string.Format(timelineFormat, screenName);
        HttpWebRequest timeLineRequest = (HttpWebRequest)WebRequest.Create(timelineUrl);
        var timelineHeaderFormat = "{0} {1}";
        timeLineRequest.Headers.Add("Authorization", string.Format(timelineHeaderFormat, twitAuthResponse.token_type, twitAuthResponse.access_token));
        timeLineRequest.Method = "Get";
        WebResponse timeLineResponse = timeLineRequest.GetResponse();
        var timeLineJson = string.Empty;
        using (authResponse)
        {
            using (var reader = new StreamReader(timeLineResponse.GetResponseStream()))
            {
                timeLineJson = reader.ReadToEnd();
            }
        }
        JArray tweets = JArray.Parse(timeLineJson);
        return (from t in tweets
            select new Tweet
            {
                date = DateTime.ParseExact((string)t["created_at"], "ddd MMM dd HH:mm:ss +ffff yyyy", new System.Globalization.CultureInfo("en-US")),
                link = t["entities"]["urls"].Count() > 0 ? (string)t["entities"]["urls"][0]["url"] : "",
                tweet = LinkUpTweet((string)t["text"]),
                author = (string)t["user"]["name"],
                screenname = (string)t["user"]["screen_name"],
                tweetLink = string.Format(@"https://twitter.com/{0}/status/{1}", screenName, (string)t["id_str"])
            }).ToList();
    }
    catch (Exception ex)
    {
        // Send Email Error
        return new List<Tweet>();
    }

错误发生在WebResponse authResponse = authRequest.GetResponse();，但我不知道如何解决这个问题。

将以下内容添加到 web.config 与结果无关

<system.diagnostics>
   <switches>
       <add name="System.Net" value="0"/>
   </switches>
</system.diagnostics>

这里有什么建议吗？

谢谢！
