I have hangfire dashboard working properly on local environment. Now, I'm trying to setup it as a container (pod) inside my cluster, deployed to azure so I can access hangfire dashboard through its url. However, I'm having issue access to it.

Below is my setup:

        [UsedImplicitly]
        public void Configure(IApplicationBuilder app)
        {
            var hangFireServerOptions = new BackgroundJobServerOptions
            {
                Activator = new ContainerJobActivator(app.ApplicationServices)
            };

            app.UseHealthChecks("/liveness");
            app.UseHangfireServer(hangFireServerOptions);

            app.UseHangfireDashboard("/hangfire", new DashboardOptions()
            {
                AppPath = null,
                DashboardTitle = "Hangfire Dashboard",
                Authorization = new[]
                {
                    new HangfireCustomBasicAuthenticationFilter
                    {
                        User = Configuration.GetSection("HangfireCredentials:UserName").Value,
                        Pass = Configuration.GetSection("HangfireCredentials:Password").Value
                    }
                }
            });

            app.UseHttpsRedirection();
            app.UseRouting();
            app.UseAuthorization();
            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllers();
            });

            HangfireJobScheduler.ScheduleJobs(app.ApplicationServices.GetServices<IScheduledTask>()); //serviceProvider.GetServices<IScheduledTask>()
        }

      secretName: task-scheduler-tls-production        

I'm trying to access the dashboard by running: example.com/hangfire, but got 503 Service Temporarily Unavailable.

I'm checking logs on the pod. Every seem to be fine:

...
...
Content root path: /data
Now listening on: http://0.0.0.0:80
Now listening on: https://0.0.0.0:443
Application started. Press Ctrl+C to shut down.
....

Would anyone know what I'm missing and how to resolve it ? Thank you
