I tried also the settings .htaccess:

<IfModule mod_rewrite.c>
   RewriteEngine on
   RewriteBase /modules/
   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteCond %{REQUEST_FILENAME} !-d
   RewriteRule . /modules/index.php [L]
</IfModule>  

but it makes no results. Settings siteurl and home are https://host/modules/. I’d be glad to some advice.

server {
  listen 80;
  server_tokens off;

  location / {
    return 301 https://$host$request_uri;
  }
}

domain.conf:

server {
  listen 443 ssl;
  server_name domain.com;

  server_tokens off;

  *ssl settings*

  location /modules/ {
    proxy_pass https://modules/;
    proxy_redirect        off;
    proxy_set_header      X-Real-IP $remote_addr;
    proxy_set_header      X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header      X-Forwarded-Proto $scheme;
    proxy_set_header      Host $host;
  }

  location / {
    proxy_pass https://platform:3000;
    proxy_redirect        off;
    proxy_set_header      X-Real-IP $remote_addr;
    proxy_set_header      X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header      Host $host;
  }
}
