NGINX post requests not working after slash how to fix?

Question

PHP

Let's say the site: site.com/
if you send POST requests: site.com/test - then everything works fine
if you do this: site.com/test/test 404 error
Router on php Macaw and on 1 server everything works fine on the other no
GET requests all work out completely
. All links are processed through index.php, since it loads the router.
Debian 8 system + NGINX + 1.10.3 + PHP-7.0-FMP + PERL

Answer 1

Nginx redirects /test/test request to index.php
Why index.php returns 404 is another matter entirely.
PS You can throw out redundant set $root_path, alias
