All internal pages give 404 error after switching to nginx, is there something wrong with the setting?

Question

Nginx

Prior to this, there were no problems with Apache. Now on nginx, only the main page is available, the rest are 404 errors.
Here is the nginx config:
server {
listen 80 default_server;
listen [::]:80 default_server;
root /var/www;
index index.php index.html index.htm index.nginx-debian.html;
server_name site.ru;
location / {
try_files $uri $uri/ = 404;
}
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/run/php/php7.2-fpm.sock;
}
}
