Laravel Nginx PHP FPM error, permission denied 13

Doesn't matter what the owner/group is really. What does this show?

ls -lah index.php

You can always do chmod 644 index.php if it's not readable for owner/group. Also make sure your webserver is running under www-data. Most of the time nginx uses nginx user.

You can verify if the nginx is running with the www-data user onnginx.conf in /etc/nginx/nginx.conf. Try to locate user, usually is in the first line of the file.

Experiencing this issue. I checked the permissions for the index.php file and outputs:

-rw-r--r-- 1 www-data root 1.7K Jun 19 2023 sickofmetal/public/index.php

The user stated in www.conf file is

user = www-data
group = www-data
listen.mode = 0660

However, there is still a problem with this user being able to open or even do "cat" on index.php.

The browser shows "404 Not Found" and the error log is this:

2024/02/28 08:49:20 [crit] 3080#3080: *1 stat() "/root/sickofmetal/public/index.php" failed (13: Permission denied), client: 127.0.0.1, server: localhost, request: "GET / HTTP/1.1", host: "localhost"

Running this: sudo -u www-data cat index.php won't open. cat: index.php: Permission denied So, while the file "index.php" belongs to user www-data, and this can read and write to the file, why can't it open it via the cat command?

I'd like to update permissions for www-data user to access the file. I'm also, learning as I'm researching on this topic so I'm not sure if I'm getting all of this.
