  Hi,

  Have you followed this document to integrate SignalR into your project <a class="postlink" href="https://aspnetboilerplate.com/Pages/Documents/SignalR-AspNetCore-Integration">https://aspnetboilerplate.com/Pages/Doc ... ntegration</a> ? Becasue .NET Core version of AspNet Zero doesn't have SignalR yet.

  Thank you for your reply.

  I am actually using Abp.Web.SignalR. The ASP.NET Zero template I am using is version 2.2.2.

  SIgnalR itself works, except when load balanced. This is how I configure SignalR:

  public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
          {
              //Initializes ABP framework.
              app.UseAbp(options =>
              {
                  options.UseAbpRequestLocalization = false; //used below: UseAbpRequestLocalization
              });
  
              if (env.IsDevelopment())
              {
                  app.UseDeveloperExceptionPage();
              }
              else
              {
                  app.UseStatusCodePagesWithRedirects("~/Error?statusCode={0}");
                  app.UseExceptionHandler("/Error");
              }
  
              app.UseAuthentication();
              app.UseJwtTokenMiddleware();
  
              if (bool.Parse(_appConfiguration["IdentityServer:IsEnabled"]))
              {
                  app.UseIdentityServer();
              }
  
              app.UseStaticFiles();
              app.UseAbpRequestLocalization();
  
  #if FEATURE_SIGNALR
              //Integrate to OWIN
              app.UseAppBuilder(ConfigureOwinServices);
  #endif
  
              app.UseSession();
  
              app.UseMvc(routes =>
              {
                  routes.MapRoute(
                      name: "defaultWithArea",
                      template: "{area}/{controller=Home}/{action=Index}/{id?}");
  
                  routes.MapRoute(
                      name: "default",
                      template: "{controller=Home}/{action=Index}/{id?}");
              });
          }
  
  #if (FEATURE_SIGNALR)
          private void ConfigureOwinServices(IAppBuilder app)
          {
              app.Properties["host.AppName"] = "MyApp";
              app.UseAbp();
  
              //added based on this https://github.com/aspnetboilerplate/aspnetboilerplate/issues/1962
              GlobalHost.DependencyResolver.Register(typeof(IAssemblyLocator), () => new SignalRAssemblyLocator());
  
              // configure SignalR to use Redis backplane
              GlobalHost.DependencyResolver.UseRedis(_appConfiguration.GetRedisConnectionString(), 6379, "", "MyQueue");
              app.MapSignalR();
  
          }

  @devkev2403 probably the problem is related to SignalR itself. Have you searched it on the web ?

  Yes, I have spent quite a lot of time on this issue. I have done a lot of research and as per my previous post I have:

  Put data protection keys in Redis (not sure SignalR uses them) Made machine keys the same on both servers Have the app pool on both servers running as the same user

  I'm not sure where the problem lies - just wondered if you have any ideas?

  I will keep investigating.

  Hi,

  If you haven't seen this, Microsoft has an official document <a class="postlink" href="https://docs.microsoft.com/en-us/aspnet/signalr/overview/performance/scaleout-with-redis">https://docs.microsoft.com/en-us/aspnet ... with-redis</a>. It might help you.
