  Hi,

  You did a wrong thing:

  HttpApi.Host URL is https://localhost:44388

  And you have to change the hub route:

  

  On the Blazor side, you are using the wrong URL to connect:

  

  Should be https://localhost:44388/my-messaging-hub.

  Try:

  if (tokenResult.TryGetToken(out var token))
  {
      hubConnection = new HubConnectionBuilder()
      .WithUrl("https://localhost:44388/my-messaging-hub", options =>
      {
          options.AccessTokenProvider = () => Task.FromResult(token.Value);
      }).Build();
  
      hubConnection.On<string>("MessageBackToBlazor", (message) =>
                                                                  {
                                                                      Console.WriteLine("Received message from server: " + message);
                                                                      // Comes from Host
                                                                      var encodedMsg = $"Message: {message}";
                                                                      messages.Add(encodedMsg);
                                                                      StateHasChanged();
                                                                  });
      await hubConnection.StartAsync();
  
      await hubConnection.InvokeAsync("SendMessage", "Hello from Blazor!");
  
      state = hubConnection.State.ToString();
  }
