ASP.NET Core SignalR redis backplain

Question

signalR hubs on multiple servers cannot communicate

I'm working here as an example: https://learn.microsoft.com/en-us/aspnet/core/signalr/scale?view=aspnetcore-2.2

communication is provided on a single server. redis connection pub / sub is working properly

I want to communicate on the hubs in the same projects on multiple servers

public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc();
        var signalR = services.AddSignalR();
        signalR.AddStackExchangeRedis(options =>
        {
            options.Configuration.ChannelPrefix = "ChannelName";
            options.Configuration.EndPoints.Add("127.0.0.1", 6379);
            options.Configuration.ClientName = "ClientNameSignalR";
            options.Configuration.AllowAdmin = true;
        });
    }
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }
        app.UseStaticFiles();
        app.UseSignalR(config =>
        {
            config.MapHub<MessageHub>("/message");
        });
        app.UseMvc();
    }
