使用System.Net.Http.HttpClient时,服务器返回无效或无法识别的响应错误

最近我将我的代码库从.net core 1.0迁移到了2.0.之后,我收到错误"服务器在随机使用System.Net.Http.HttpClient时返回了无效或无法识别的响应错误".我在100个请求中的2个中收到此错误.

另外如何调试这个,因为它是随机发生的:(

Program.cs中

public class Program
    {
        public static void Main(string[] args)
        {
            var cOnfig= new ConfigurationBuilder()
            .AddJsonFile(Path.Combine(Directory.GetCurrentDirectory(),"hosting.json"), optional: false)
            .Build();

            var useHttps = false;

            bool.TryParse(config !=null  ? config["useHttps"] : "false", out useHttps);

            IWebHost host = null;
            if (useHttps)
            {
                var fileInfo = new FileInfo(config["certName"]);
                X509Certificate2 cert = new X509Certificate2(fileInfo.FullName, config["certPwd"]);

                host = new WebHostBuilder()
                    .UseContentRoot(Directory.GetCurrentDirectory())
                    .UseStartup()
                    .UseKestrel(optiOns=>
                    {
                        options.Listen(IPAddress.Loopback, 5000);
                        options.Listen(IPAddress.Any, 4430, listenOptiOns=>
                        {
                            listenOptions.UseHttps(cert);
                        });
                    })
                    .UseIISIntegration()
                    .Build();
            }
            else
            {
                host = new WebHostBuilder()
                    .UseStartup()
                    .UseKestrel()
                    .UseContentRoot(Directory.GetCurrentDirectory())
                    .UseIISIntegration()
                    .UseUrls(config["url"])
                    .Build();

            }
            host.Run();


        }
    }
