来自.net的错误调用API“无法创建SSL/TLS安全频道”。

Question

当调用某些API时，我会从下面的代码中获取“无法创建SSL/TLS安全频道”（可用于某些API），但仅在从Windows 2012 Server运行时。它在我的笔记本电脑上正常工作。我发现的另一件事是，我可以从服务器上称为邮递员的失败API罚款，但是如果我使用PowerShell，则会失败。

它似乎与.NET有关，但我尝试更新为.NET 4.8而没有任何成功。

对还要尝试什么想法？

Console.WriteLine("Make Reuest Starting");
            if (!string.IsNullOrWhiteSpace(generalConfig?.ProxyAddress))
            {
                WebProxy webProxy = new WebProxy(generalConfig.ProxyAddress);
                webProxy.Credentials = new NetworkCredential(generalConfig.ProxyUsername, generalConfig.ProxyPassword,
                    generalConfig.ProxyDomain);
                WebRequest.DefaultWebProxy = webProxy;
            }
            ServicePointManager.SecurityProtocol |= SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;
            WebRequest request = WebRequest.Create(apiUrl) as HttpWebRequest;
            request.Timeout = 40000;

            if (!(string.IsNullOrWhiteSpace(username) || string.IsNullOrWhiteSpace(password)))
            {
               
                request.Credentials = new NetworkCredential(username, password);
            }
            Console.WriteLine("Pre web request log");
            using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
            {
                Console.WriteLine(response.StatusCode);
                using (StreamReader reader = new StreamReader(response.GetResponseStream()))
                {
                    responseData = reader.ReadToEnd();
                    //Console.WriteLine(responseData);
                }
            }
