Hello Dears I am trying to use signalR with nopcommerce 4.2 but it is not working with me . I have created Hub class and html and javascript needed code I have added signalR to startup.cs file like this. public IServiceProvider ConfigureServices(IServiceCollection services) { services.AddSignalR(); return services.ConfigureApplicationServices(_configuration, _hostingEnvironment); } public void Configure(IApplicationBuilder application) { application.ConfigureRequestPipeline(); application.UseSignalR(routes => { routes.MapHub<Chat>("/chat"); }); } I am following this article : https://codingblast.com/asp-net-core-signalr-simple-chat/ Is that something wrong I do or something I need to do further to make it work ? It is giving me some client side error when the page running I am showing below : signalr.js:3088 [2020-02-05T09:13:12.725Z] Information: Normalizing '/chat' to 'http://localhost:15536/chat'. signalr.js:4709 WebSocket connection to 'ws://localhost:15536/chat?id=lvRemXeWLWEoxKZgOPXzHQ' failed: Error during WebSocket handshake: Unexpected response code: 302 (anonymous) @ signalr.js:4709 signalr.js:3082 [2020-02-05T09:13:12.921Z] Error: Failed to start the transport 'WebSockets': Error: There was an error with the transport.
