403 Seção ninjx cakephp admin proibida

Question

Eu tenho o nginx instalado no ubuntu com o cakephp instalado no vhost. O site está funcionando bem, mas ocorreu um erro 403 Proibido ao tentar acessar a seção domain.com/admin.

Arquivo de configuração do Nginx: -

server {
    listen   80;
    #listen   [::]:80;

    root /var/www/downloads.studyiq.com/html/webroot;
    index index.php index.html;

    server_name downloads.studyiq.com;

    #location / {
    #       try_files $uri $uri/ /index.php?$args;
    #}

    location /webroot/admin/ {
            rewrite ^(/.*)$ /var/www/downloads.stuqyiq.com/html/webroot/$1 break;
