Why doesn't DLE (Nginx + Apache2) work?

Question

Nginx

Please help, I decided to make Nginx as a static frontend and Apache as a backend, everything seems to work, but after authorization and going to any page, DLE throws it to the authorization page (if you are in the PU) or simply exits the account (if you move between tabs on the main page), also noticed that in the DLE PU, when trying to clear the cache, it gives an "Error" error.
Here is my nginx config: https://paste.dimdev.org/wuhajanuvi.nginx
