Issue getting real client's ip on laravel 12 docker container

I'm trying to get the IP of the client that's making a registration request, but when I try to get the data from code, I get the address of the Docker container. I made the following changes:

bootstrap/app.php

    ->withMiddleware(function (Middleware $middleware) {
        $middleware->prepend(TrustProxies::class);
    })

.env

    TRUST_PROXIES=*
    TRUST_PROXIES_HEADERS=HEADER_X_FORWARDED_FOR

app.conf (Nginx)

    server {
    listen 80;
    server_name localhost;

    root /var/www/public;
    index index.php index.html;

    location / {
        try_files $uri $uri/ /index.php?$query_string;

        proxy_set_header Host $host;
        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;
    }

    location ~ \.php$ {
        fastcgi_pass app-AxsSEMEFO:9000;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

        # Asegúrate de pasar los headers como variables correctas
        fastcgi_param HTTP_X_FORWARDED_FOR $proxy_add_x_forwarded_for;
        fastcgi_param HTTP_X_REAL_IP $remote_addr;
        fastcgi_param HTTP_X_FORWARDED_PROTO $scheme;
    }
}

and through this i do test

    Route::get('/debug-ip', function () {
    return response()->json([
        'Laravel IP' => request()->ip(),
        '_SERVER["HTTP_X_FORWARDED_FOR"]' => $_SERVER['HTTP_X_FORWARDED_FOR'] ?? 'not set',
        '_SERVER["X_FORWARDED_FOR"]' => $_SERVER['X_FORWARDED_FOR'] ?? 'not set',
        'headers' => request()->headers->all(),
    ]);
    });

to get this:

{
  "Laravel IP": "172.18.0.1",
  "_SERVER[\"HTTP_X_FORWARDED_FOR\"]": "172.18.0.1",
  "_SERVER[\"X_FORWARDED_FOR\"]": "not set",

  }

I'm not really an expert on Docker, so any help is welcome. If you need more information, please let me know.

Thanks in advance.
