Not able to connect from javascript signalr client to azure client

Question

Here is my stuff:

Javascript:

 var connection = new signalR.HubConnectionBuilder()
                .configureLogging(signalR.LogLevel.Debug)
                .withUrl("/client/?hub=myHub")
                .withAutomaticReconnect().build();

OR

 var connection = new signalR.HubConnectionBuilder()
                .configureLogging(signalR.LogLevel.Debug)
                .withUrl("https://azure-service.service.signalr.net/client/?hub=myHub")
                .withAutomaticReconnect().build();

C# Startup.cs:

    // Azure SignalR service
    app.UseAzureSignalR(routes =>
    {
        routes.MapHub<MyHub>("/myHub");
    });

Its getting following error: 400 - https://localhost:44324/client/negotiate?hub=myHub&negotiateVersion=1 Failed to complete negotiation with the server: Error

You need add ConnectionString in appsettings.json. It works for me. You also can download my sample code.
