I upload image to laravel backend, store the file to path storage/app/public.
Now I can see this file under path.
<PROJECT>/storage/app/public# ls
notefeel_5e3ecd40d7e68.jpeg
But when I access the image from browser with link https://www.notefeel.com/storage/notefeel_5e3ecd40d7e68.jpeg, 404 return.
Solution
Run
php artisan storage:link
Then the image was shown in browser.
