C# ASP.NET核心Linux SSL-SSL读取Bio失败，出现OpenSSL错误

我目前正在开发一个asp.net核心应用程序。应用程序本身在Windows下使用Kestrel运行得非常完美。现在，我将应用程序发布到linux环境（Lubuntu 16.04.1 64位）

向所有内容发出正常http请求时，一切正常

当我通过https调用页面时，一切正常，但通过wss建立的WebSocket连接立即关闭。还发现（多亏了）在没有响应主体的情况下进行状态码响应会产生该错误。但我很确定两者都有不同的起源。Websocket错误似乎发生在升级响应时。问题已报告给WebSockets Github Repo（）。报告状态代码错误

在program.cs中，我将Kestrel配置为使用ssl

IConfigurationRoot config = new ConfigurationBuilder()
            .SetBasePath(Directory.GetCurrentDirectory() + "/Config")
            .AddJsonFile("appsettings.json")
            .Build();

        IWebHost host = new WebHostBuilder()
            .UseConfiguration(config)
            .UseContentRoot(Directory.GetCurrentDirectory())
            .UseKestrel(options =>
            {
                options.NoDelay = true;
                options.UseHttps(new X509Certificate2(Directory.GetCurrentDirectory() + config["SSL:Cert:Path"], config["SSL:Cert:Password"])); //Currently set to 'cert.pfx' with pw 'cert'
            })
            .UseIISIntegration()
            .UseStartup<Startup>()
            .Build();

        host.Run();

如前所述。。。在windows上，一切正常。。。只有linux在制造问题

我的openssl版本是：

OpenSSL 1.0.2g-fips 2016年3月1日

这台机器上的OpenSSL版本是什么？OpenSSL版本的结果是：OpenSSL 1.0.2g-fips 2016年3月1日我在一个带有https和kestrelCorefx的非websocket请求上看到了相同的错误。这里提出的问题我在这里描述的问题与websocket有关。当我禁用它们时，一切正常。我已经为WebSocket的回购发行了一期：。看来他们已经知道这个问题了。

        if (context.WebSockets.IsWebSocketRequest)
        {
            WebSocket socket = await context.WebSockets.AcceptWebSocketAsync();

            if (socket != null && socket.State == WebSocketState.Open)
            {
                 ArraySegment<byte> buffer = new ArraySegment<byte>(new byte[4096]);
                 await socket.ReceiveAsync(buffer, CancellationToken.None);

                 ... followed by handling of the message ... gets never called
            }
        }
