PHP - Laravel 404在公共/存储中

I am trying to access a file placed in my public storage with a basic HTTP get request. The file is located here:

www.example.com/doccenter/file.pdf

However, when I try to load that page I get a 404 Error - Not Found page.

I have tried to run:

php artisan storage:link

But still not working. I have validated that the file does indeed exist:

$ ~/example.com/storage/app/public/doccenter -ls

shows:

file.pdf

What am I doing wrong here?

Per the docs, php artisan storage:link creates a link to storage/app/public at example.com/storage, so your file is likely at www.example.com/storage/doccenter/file.pdf.
