Laravel 5.4 - IIS 10.0 root route issue

I am using laravel 5.4 and deployed this to IIS 10.0.

The root route is not working on IIS but same is working fine for php artisan serve.

Below is my route:

Route::get('/', function () { return view('welcome'); });

Please reply what i need to change.

Thanks in advance.
