I have installed Hangfire in my .NET Core 2.1 application but when I attempt to display the dashboard on my development PC all I get is a blank screen. My application is configured as follows;

public void ConfigureServices(IServiceCollection services)
{
     services.AddHangfire(x => x.UseSqlServerStorage("Server=localhost;Database=PWTT-DEV;Integrated Security=True;MultipleActiveResultSets=True"));
}

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    app.UseHangfireServer();
    app.UseHangfireDashboard();
}

I have also tried;

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    app.UseHangfireServer();
    app.UseHangfireDashboard("/hangfire", new DashboardOptions
    {
        Authoization = new [] { new MyAuithorizationFilter() }
    });
}

public class MyAuthorizationFilter : IDashboardAuthorizationFilter
{
    public bool Authorize(DashboardContext context)
    {
            return true;
    }
}

Can anyone suggest what is wrong with the configuration?
