Controller in folder - method not accessible unless I set a route on Linux - Windows OK

[daljit3]

I have got a test site setup on my local Windows system and same site uploaded on a server with Ubuntu.

On my local - URLs mysite/admin/home/upload and mysite/admin/upload both work fine.

However, on my Ubuntu server, mysite/admin/home/upload throws up 404 error saying Controller or its method is not found: App\Controllers\Admin::home [i.e. its looking for an admin controller and it's home method rather than Home controller in an admin folder]
I don't have any issues with mysite/admin/upload as I believe the route below is parsing correctly.

What's going wrong here? Here are my routes.

$routes->setAutoRoute(true);

$routes->group('admin', ['namespace' => 'App\Controllers\admin'], function($routes)
{
    $routes->add('/', 'Home::index', ['as' => 'admin.home']);
    $routes->add('upload', 'Home::upload', ['as' => 'admin.upload']);
});

Just to add into the above - On Ubuntu server, if the controllers at App/Controllers dont have any issues i.e. I am able to access with mysite/controllername/methodname or mysite/route-name without any issues. So it's an issue with folders only.

The namespace segments (and their respective folders) are expected to be ucfirst. Here's an article I wrote up on namespaces in CI4.
