Error connecting to Postgres database, but can connect on pgadmin

Im having this error when trying to connect to the database:

[auth][cause]: error: password authentication failed for user "user"

But i can connect to pgadmin normaly with the same credentials so I dont undertand whats going on.

docker-compose.yaml

services:
  postgres:
    image: postgres:latest
    container_name: postgres
    restart: always
    environment:
      POSTGRES_DB: auth_db
      POSTGRES_USER: user
      POSTGRES_PASSWORD: password
    ports:
      - "5432:5432"
    volumes:
      - postgres_data:/var/lib/postgresql/data

  pgadmin:
    image: dpage/pgadmin4
    container_name: pgadmin
    restart: always
    environment:
      PGADMIN_DEFAULT_EMAIL: user@example.com
      PGADMIN_DEFAULT_PASSWORD: password
    ports:
      - "5050:80"
    volumes:
      - pgadmin_data:/var/lib/pgadmin
    depends_on:
      - postgres

volumes:
  postgres_data:
  pgadmin_data:

.env

AUTH_DATABASE_HOST="localhost"
AUTH_DATABASE_PORT=5432
AUTH_DATABASE_NAME="auth_db"
AUTH_DATABASE_USER="user"
AUTH_DATABASE_PASSWORD="password"

pool:

import { Pool } from "pg";

export const pool = new Pool ({
    host: process.env.AUTH_DATABASE_HOST,
    port: parseInt(process.env.AUTH_DATABASE_PORT!, 10), // 10 TO MAKE IT A BASE10
    database: process.env.AUTH_DATABASE_NAME,
    user: process.env.AUTH_DATABASE_USER,
    password: process.env.AUTH_DATABASE_PASSWORD,
})

I tryed to connect directly to the database and got the same error:

psql -h localhost -U user -d auth_db Password for user user: psql: error: connection to server at "localhost" (::1), port 5432 failed: FATAL: password authentication failed for user "user"

But for some reason it works with pgadmin.

Im using windows and docker desktop with Hyper-V (no wsl)

idk if it helps but this are the user permissions:

"user" "auth_db" "public" "users" "INSERT" "user" "auth_db" "public" "users" "SELECT" "user" "auth_db" "public" "users" "UPDATE" "user" "auth_db" "public" "users" "DELETE" "user" "auth_db" "public" "users" "TRUNCATE" "user" "auth_db" "public" "users" "REFERENCES" "user" "auth_db" "public" "users" "TRIGGER"

Check if you have a running postgres.exe service from installing postgres on your Windows machine directly. This will prevent you from connecting to the postgres from the docker container.
