Laravel 5.5: Unable to retrieve the URL of uploaded image file

My uploaded file(abc.png) is being saved in the folder storage\app\public\uploaded_files\abc.png

When I use $url = Storage::disk('public')->url($business->logo); it generates http://127.0.0.1:8000//storage/abc.png which rather opens a URL related to a route. In filesystem.php I have the following entry.

'public' => [
            'driver' => 'local',
            'root' => storage_path('app/public'),
            'url' => env('APP_URL').'/storage',
            'visibility' => 'public',
        ],

Route is given below: Route::get( '/{business_slug}/{item_name}-{encoded_id}', 'ItemController@single' )->name( 'single_item' );

What should I do to fix the image URL and make it available publicly?
