Nginx location with alias redirect to root [closed]

I need to place a site inside existed project. site.com – this is the main site, site.com/site2/ this is the second one.

1. When I visite site.com it’s show me /index.php [OK]
2. When site.com/site2/ it’s show me /site2/web/index.php [OK]
3. But when site.com/site2/qwe it redirect back to /index.php [FAIL]. I need /site2/web/index.php

The project structure is:

/
/site2/
/site2/web/
/site2/web/index.php
/index.php

Nginx site conf

server {
    root /var/www/site;
    index index.php index.html index.htm;
    ...

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

    location ~ .php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/run/php/php7.4-fpm.sock;
    }

    location /site2/ {
        alias /var/www/site/site2/web/;

        add_header X-Location-Visited true always;

        try_files $uri $uri/ /index.php$is_args$args;
        # I'd tried without any result
        # try_files $uri $uri/ /site2/index.php$is_args$args;
        # try_files $uri $uri/ /site2/web/index.php$is_args$args;

        location ~ .php$ {
            include snippets/fastcgi-php.conf;
            fastcgi_param SCRIPT_FILENAME $request_filename;
            fastcgi_pass unix:/run/php/php7.4-fpm.sock;
        }
    }
}

snippets/fastcgi-php.conf
