Laravel private file serving pending problem

I save some photos privately in the storage and show them to the user when needed using the following method.

in route :

Route::get('/serveFile/{address?}', [FileController::class, 'serveFile'])
->where('address', '.*')->name('serveFile');

in controller :

public function serveFile($address = null)
{
    return response()->file(storage_path($address));
}

finally, the src of the photo or file or … is placed in the html as follows:

https://DOMAIN/serveFile/app/DIRECTORYNAME/2024/06/15/DIRECTORYNAME/NAME.jpg

Everything is good and there is no problem in loading and working logic. Only when I want to show a large number of images, the browser puts them in a queue and makes them pending and loads the images two by two.
look at this picture :

Images with lazy load and without it, both modes have problems.

What is wrong?

i tried changing controller code and increasing CPU count and change hosting. nothing changed.
i need some advise 🙂
