I have a web api that receive response from payment bank gateway and I want to send this response to my angular app through signalR,
but angular not receive it, and redirect to my web api Uri.

        await _hubContext.Clients.All.SendAsync("ReceiveMessage", result.Data);            

my hup:

 public class MyHub : Hub
 {
     public async Task SendMessage(string message)
     {
         try
         {
     
             await Clients.All.SendAsync("ReceiveMessage", message);
         }
         catch (Exception ex)
         {

             Console.WriteLine(ex.Message);
         }
     }
 }

my angular code :

  @Output() onSignalRMessage: EventEmitter<any> = new EventEmitter();

  constructor(private router: Router) {
    this.startConnection();
    this.receiveMessage();
  }
  public startConnection = () => {
    console.log('Starting connection...');
    this.hubConnection = new signalR.HubConnectionBuilder()
      .withUrl('https://localhost:5033/myHub'
        , {      
          accessTokenFactory: () => localStorage.getItem('tax-cookie')
        })
      .build();
   
    this.hubConnection.start()
      .then(() => console.log('Connection started'))
      .catch(err => console.log('Error while starting connection: ' + err));
  }

  receiveMessage = () => {

    this.hubConnection.on('ReceiveMessage', (message: string) => {
      console.log('receiveMessage: ' + message);

      this.paymentStatusSubject.next(message);
      this.onSignalRMessage.emit(this.paymentStatusSubject);

    });
   
  }
  public addTransferChartDataListener() {
    this.hubConnection.on('ReceiveMessage', (data) => {
      console.log('ReceiveMessage: ' + data);
    });
  }
}

app.component.ts :

export class AppComponent {
 
  private hubConnection: signalR.HubConnection;
  constructor(
    private signalRService: SignalRService,
    private router: Router
  ) { }
  public messages = [];
  ngOnInit() {
   this.signalRService.onSignalRMessage.subscribe((data) => {
     
        this.messages.push(data);
         console.log('receiveMessage: ' + this.messages[0]);
      })
    }
