Why don't .htaccess rules work?

Question

Apache HTTP Server

The server works in conjunction with apache + nginx. If you write some simple rule, then it works, for example: "RewriteRule ^ www.google.com " and put it in site.ltd/affiliates/
Then when you open site.ltd/affiliates/ it redirects correctly, but if you open any folder inside the site.ltd/affiliates/ folder, for example site.ltd/affiliates/scripts/jobs.php - the redirect doesn't work, so the rules don't seem to work where they should.
Specifically, the request:
site.ltd/affiliates/accounts/default1/banners/NotE...
should be redirected to:
site.ltd/affiliates/scripts/file.php?file=banners/...
but that doesn't work . If I open the first link, I will see a 404 error, and the second link leads to a small 1*1 pixel image.

Answer 1

The problem turned out to be nginx, as it took all the static and did not give it to apache. I solved the problem by editing the nginx config.
