Signalr Hub Connection timing out #10498 | Support Center

Astech created 3 years ago

Hi,

I'm trying to get a Signalr Client Hubconnection working on Xamarin but only receiving timeouts.

The Hubconnection works fine on the web application:

Information: Normalizing '/signalr-document-conversion' to 'https://localhost:44302/signalr-document-conversion'. WebSocket connected to wss://localhost:44302/signalr-document-conversion?id=b8_kizi_mCESajbklz7pyQ.

The Xamarin code:

` try { HubConnection = new HubConnectionBuilder() .WithUrl("https://192.168.0.22:44302/signalr-document-conversion" ).ConfigureLogging(logging => { logging.SetMinimumLevel(LogLevel.Debug); logging.AddConsole(); logging.AddDebug(); }) .Build();

            HubConnection.On<int, int>("DocumentReordered", (documentId, newOrderIndex) =>
            {
                Console.WriteLine("TEST");
            });

            HubConnection.On<int, string, string, string>("DocumentStatusChanged", (documentId, status, fileName, fileTypeImageName) =>
            {
                Console.WriteLine("TEST");
            });

            await HubConnection.StartAsync();
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex);
        }

The log

The Xamarin app is being run from a phone and the webhost is on a pc. I'm able to connect to all the other services from the phone just fine.

Hi,

Could you add this Mobile profile to your MVC project's launchSettings https://github.com/aspnetzero/aspnet-zero-core/blob/dev/aspnet-core/src/MyCompanyName.AbpZeroTemplate.Web.Host/Properties/launchSettings.json#L18 and run your project with Mobile profile and try again ?

Hi,

I tried using the mobile profile on MVC and had no different result.

I am currently running 3 projects, HOST, MVC and DROID. The SignalR connection works fine for MVC to HOST but not DROID to HOST.

Hi @Astech

Do you have app.UseHttpsRedirection(); in your Startup.cs ? If so, could you disable it and try again ?

HI @ismcagdas

I have tried disabling that line however when I startup my xamarin app whilst the mvc/host are running I get the following exception regardless of that line of code:

Hi @Astech

Does that work when you use the http URL (http://192.168.0.22:44301/signalr-document-conversion) ?

Hi @Astech

Everything seems normal in your case. As a last request, could you share your signalr-document-conversion definition on server side ?

I think your app works wihtout the signalR connection, right ? I mean the device can connect to server side api ?

Thanks,

Astech created 3 years ago

Hi,

Yes the app works fine connecting to the api.

These are the snippets, let me know if this is what you expected to see:

` public class DocumentHub : Hub { }

app.UseEndpoints(endpoints =>
{
    endpoints.MapHub<AbpCommonHub>("/signalr");
    endpoints.MapHub<DocumentHub>("/signalr-document-conversion");

    endpoints.MapControllerRoute("defaultWithArea", "{area}/{controller=Home}/{action=Index}/{id?}");
    endpoints.MapControllerRoute("default", "{controller=Home}/{action=Index}/{id?}");

    }
});

await _documentHub.Clients.All.SendAsync("DocumentStatusChanged", document.Id, document.Status.ToString(), document.FileName, document.FileTypeImageName);`
