Admin local login only with Nginx Proxy Manager

[Buzzi]

I've tried various things, here's where I am.

My steup :
- The PC is on Windows 11.
- Jellyfin is just install on Windows
- NPM is install via Docker Compose and Docker Desktop

Here is the .yml

Code:

version: '3.8'
services:
  app:
    image: 'jc21/nginx-proxy-manager:latest'
    container_name: NPM
    restart: unless-stopped
    ports:
      # These ports are in format <host-port>:<container-port>
      - '80:80' # Public HTTP Port
      - '443:443' # Public HTTPS Port
      - '81:81' # Admin Web Port

    volumes:
      - C:\Docker\Nginx\data:/data
      - C:\Docker\Nginx\letsencrypt:/etc/letsencrypt
      - C:\Docker\Nginx\_hsts.conf:/app/templates/_hsts.conf:ro

The machine's IP is : 192.168.1.20
NPM's IP is : 172.18.0.2 (obtained with the command "docker inspect NPM | findstr IPAddres"
Docker Desktop's IP is : 192.168.65.0/24


I tried all possible IP combinations in "Known Proxies". they all allow remote connection.
Here are the client IPs obtained :
