nginx config, 403 forbidden error. Why can't nginx see index.php in the public folder?

Question

Nginx

Nginx gives a 403 error, for some reason it does not see index.php in the public folder, but if you create index.php in the root of the project, right in the crm folder, everything works fine, but this is not a solution, breaking the project structure on symfony 4.
I tried to install root /var/www/crm/public , but then it already gives a 404 error

upstream php {
        server unix:/var/run/php/php7.2-fpm.sock;
}
server {
 listen 80 default_server;
        client_max_body_size 100M;
        server_name crm.at.npo;
        root /var/www/crm;
        index index.php

        server_name crm.npo-at.com;

 access_log  /var/www/crm/var/log/access.log;
 error_log  /var/www/crm/var/log/error.log;

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

 location ~ \.php$ {
                try_files $uri =404;
                fastcgi_pass php;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                include fastcgi_params;
  fastcgi_read_timeout 600;
        }

        location ~* \.(exe|rar|max|js|css|png|jpg|jpeg|gif|ico)$ {
                expires max;
                log_not_found off;
        }
}
