nginx с php-fpm возвращает 403 при переходе на сайт

Я установил серверный блок для моего сайта , работающего на Nginx на CentOS 7 VPS.

Когда я пытаюсь перейти на свой сайт, я получаю ошибка 403 Запрещено . По-видимому, это обычная проблема, но я не мог понять ответы, которые я нашел:

Nginx и PHP-FPM 403 Запрещено

Вот конфигурация nginx по умолчанию:

server {
    listen       80;
    server_name  <my server ip>;
    root /var/www/html;
    index index.php index.html index.htm;

    location / {
        try_files $uri $uri/ =404;
    }
    error_page 404 /404.html;
    error_page 500 502 503 504  /50x.html;
    location = /50x.html {
        root   /var/www/html;
    }

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }

}

Вот . conf для моего сайта:

server {
  listen 80;
  server_name nativeleaf.co.uk www.nativeleaf.co.uk;
  access_log /var/www/html/nativeleaf.co.uk/access.log combined;
  root /var/www/html/nativeleaf.co.uk;

  location ~ \.php$ {
    try_files $uri =404;
    fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;
  }
}

А вот конфигурация для php-fpm :

; Start a new pool named 'www'.
[www]

; The address on which to accept FastCGI requests.
; Valid syntaxes are:
;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific address on
;                            a specific port;
;   'port'                 - to listen on a TCP socket to all addresses on a
;                            specific port;
;   '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
;listen = 127.0.0.1:9000
listen = /var/run/php-fpm/php-fpm.sock

; Set listen(2) backlog. A value of '-1' means unlimited.
; Default Value: -1
;listen.backlog = -1

; List of ipv4 addresses of FastCGI clients which are allowed to connect.
; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original
; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address
; must be separated by a comma. If this value is left blank, connections will be
; accepted from any ip address.
; Default Value: any
listen.allowed_clients = 127.0.0.1

; Set permissions for unix socket, if one is used. In Linux, read/write
; permissions must be set in order to allow connections from a web server. Many
; BSD-derived systems allow connections regardless of permissions.
; Default Values: user and group are set as the running user
;                 mode is set to 0666
listen.owner = nginx
listen.group = nginx
listen.mode = 0750

; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
;       will be used.
; RPM: apache Choosed to be able to access some dir as httpd
user = nginx
; RPM: Keep a group allowed to write in log dir.
group = nginx

Проверка журналов

Когда я делаю tail error.log на в журналах Nginx я вижу следующее:
