Asp.net ReactionNative SignalR连接在调试模式下工作，在释放模式下失败

我有一个ASP.NET 6.0 Core Web Api with Signalr发布到Windows Server 2017上的IIS. 然后我有一个React-Native移动应用程序，它使用@microsoft/signalr连接到SignalR中心. 当移动应用程序通过Android模拟器和我的Android手机在调试模式下运行时，它可以连接到Signalr，没有任何问题. 一切都很完美. 现在，当我try 在发布模式下运行相同的应用程序时，它不工作，也无法连接. 任何 idea /帮助将不胜感激.

Program.cs Main

            builder.Services.AddCors(options =>
            {
                options.AddDefaultPolicy(builder =>
                {
                    builder.AllowAnyOrigin()
                           .AllowAnyMethod()
                           .AllowAnyHeader();
                           //.AllowCredentials()
                           //.SetIsOriginAllowed((host) => true);
                });
            }
            );

            // Add services to the container.
            builder.Services.AddControllers()
                            .AddJsonOptions(options =>
                            {
                                options.JsonSerializerOptions.PropertyNamingPolicy = JsonNamingPolicy.CamelCase;
                                //options.JsonSerializerOptions.PropertyNamingPolicy = null;
                            });


            builder.Services.AddEndpointsApiExplorer();
            builder.Services.AddSwaggerGen();
            builder.Services.AddSignalR();
            builder.Logging.ClearProviders();
            Serilog.ILogger logger = new AppLogger(builder.Configuration).Logger;
            builder.Logging.AddSerilog(logger, true);

            var app = builder.Build();
            
            // Configure the HTTP request pipeline.
            if (app.Environment.IsDevelopment() || app.Environment.IsProduction())
            {
                app.UseSwagger();
                app.UseSwaggerUI();
            }

            //app.UseHttpsRedirection();

            app.UseAuthentication();
            app.UseAuthorization();

            app.UseCors();
            app.UseWebSockets();

            app.MapControllers();
            app.MapHub<FacilityHub>("/facility-hub");

            app.Run();

我运行了以下命令，查看应用程序在发布模式下运行时的日志(log).
