Why are .php files not being processed in the Nginx + PHP-FPM bundle?

Question

PHP

Please tell me what could be the problem.
Ubuntu Server 18.04
Installed Nginx 1.14 and PHP 7.2 FPM
.html files open fine and when accessing .php just a blank page, no error.
The logs are empty, only access logs.
Host config

Host config

server {
  listen      80;
    listen      [::]:80;
  server_name site.ru www.site.ru;

    root        /var/www/site.ru;
    index       index.php index.html;
    charset     utf-8;

    location / {
        try_files $uri $uri/ =404;
    }

    location ~ \.php$ {
        fastcgi_pass  unix:/run/php/php7.2-fpm.sock;
        fastcgi_index index.php;
        include       fastcgi_params;
    }
}

php.ini standard
Changed only this
cgi.fix_pathinfo=0 (was 1)
nginx.conf config

nginx.conf config

user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

events {
  worker_connections 768;
  # multi_accept on;
}

http {
  sendfile on;
  tcp_nopush on;
  tcp_nodelay on;
  keepalive_timeout 65;
  types_hash_max_size 2048;

  server_names_hash_bucket_size 64;

  include /etc/nginx/mime.types;
  default_type application/octet-stream;

  ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
  ssl_prefer_server_ciphers on;

  access_log /var/log/nginx/access.log;
  error_log /var/log/nginx/error.log;

  gzip on;

  include /etc/nginx/conf.d/*.conf;
  include /etc/nginx/sites-enabled/*;
}

I did not touch it either, standard.
The www.conf config is also standard
. In the site directory, all folders and files were owned by www-data, before that it was root
. What could be the problem that I did not configure?
Naturally, every time I changed the configs, I rebooted both nginx and php-fpm
systemctl restart nginx && systemctl restart php7.2-fpm

Try this conf:

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

location ~ [^/]\.php(/|$) {
        fastcgi_split_path_info ^(.+?\.php)(/.*)$;
        if (!-f $document_root$fastcgi_script_name) {return 404;}
        fastcgi_param HTTP_PROXY "";
        include fastcgi_params;
        fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $request_filename;
    }
