I created this ticket in GitHub where I was able to get SignalR to work in Blazor WASM but only with the opensource version

When I try it with suite created project I get these errors. I can zip and send somebody the project.

I´m unable to spot a major difference in config that could be the cause of this and I was also unable to add EnableDetailedErrors so I could maybe get more detailed information.

    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();
}
