nginx 404 not found in subfolder - php

Question

I installed a PHP script in /files/ subfolder on Nginx but when I access the page, it's not working. Just showing 404 not found. I also tried changing the root directly to the subfolder but still not working, like this: root /home/smart/web/example.com/public_html/files;
Also, I added this in the config but not working.
location ^~ /files {
if (!-e $request_filename) { rewrite ^/(.*) /files/index.php?_page_url=$1 last; }
location ~ \.php$ {
if (!-e $request_filename) { rewrite ^/(.*) /files/index.php?_page_url=$1 last; }
fastcgi_pass unix:/run/php/php8.0-fpm-example.com.sock;
index index.php;
include /etc/nginx/fastcgi_params;
fastcgi_split_path_info ^(.+?\.php)(/.*)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param SCRIPT_FILENAME $request_filename;
}
location /files/files/ {
internal;
}
# these locations would be hidden by .htaccess normally
location /files/logs/ {
deny all;
}
}
Here is my full nginx config:
