What should I change in the nginx server config to correctly display the Wordpress multisite on subfolders?

Question

Nginx

After migrating the site to nginx, the main site works fine, but the one on the subfolder does not load resources (404 in the console), only HTML markup.
And the admin panel does not work for him, he says that the site has redirected too many times.
Apparently, some changes need to be made to the server configuration, but I still haven’t figured out which ones.
Main site: https://platinumstandardeducation.com/ Subfolder
site: https://platinumstandardeducation.com/eng
