Why does it issue - no input file specified. nginx?

Question

Nginx

Good afternoon!
There is nginx 1.14.0, ubuntu 18.04 php7.2 php7.2-fpm
I wanted to run it as usual on Centos 6 with the standard config for the web host, but for some reason it gives me such a strange error. I double-checked all the paths, the files are in their places.
I am attaching the config.
nginx

server {
        #laravel config 
        listen 80;
        server_name mystic.com www.mystic.com;
        root /vhosts/mystic/public_html/public;
        index index.php index.html index.htm;
        charset utf-8;
        access_log /vhosts/mystic/logs/nginx.access.log  main;
        error_log  /vhosts/mystic/logs/nginx.error.log error;
        fastcgi_buffers 8 16k;
        fastcgi_buffer_size 32k;

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

        location ~* \.(ico|css|js|gif|jpeg|jpg|png|woff|ttf|otf|svg|woff2|eot)$ {
                expires max;
                access_log  off;
                log_not_found  off;
        }
        location ~ \.php$ {

                fastcgi_param   SCRIPT_FILENAME  $document_root$fastcgi_script_name;
                include         fastcgi_params;
        }
        gzip on;
        gzip_min_length 1000;

        include /etc/nginx/security.conf;
}

php-fpm

[webdev]
user = webdev
group = webdev

listen = /var/run/php-fpm-$pool.sock
listen.backlog = 2048

listen.owner = webdev
listen.group = webdev
listen.mode = 0660

pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 20
pm.max_requests = 5000
pm.status_path = /phpfpm-status


slowlog = /var/log/php-fpm/$pool-slow.log
request_slowlog_timeout = 0

catch_workers_output = no

php_admin_value[error_log] = /var/log/php-fpm/$pool-error.log
php_admin_flag[log_errors] = on

php_value[session.save_handler] = files
php_value[session.save_path]    = /var/lib/php/session
php_value[soap.wsdl_cache_dir]  = /var/lib/php/wsdlcache

Before that, there was an error - Primary script unknown, i.e. when php-fpm. did not see the files, I fixed it by setting cgi.fix_pathinfo=0
If you return it, the output will be - File not found.
It is not entirely clear why this happens, because the socket file is created without any problems.
