How to assign permissions to my hosting in order to activate the Secure Location

[gonzalo]

When I enable the “Secure Location” option to isolate file uploads outside the root folder, I am getting a 404 error when uploading files. I understand that this is due to the limited permissions of my hosting, as stated in the warning message “On some servers it is not possible to use “Secure Location” outside of the site’s root folder, because of the limited permissions.”

Is there a way to activate these permissions in my hosting configuration?

What kind of permissions are they?

Im using my own server where i have full access

(I've asked in plugins support forum and slack but didn't received any feedback, maybe here I'll be luckier)
