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.

See this stackoverflow question

1.Check Environment Variables: Ensure that your application is correctly loading the environment variables. You can do this by logging the environment variables before creating the Pool: `console.log('Database Configuration:', {

host: process.env.AUTH_DATABASE_HOST,
port: process.env.AUTH_DATABASE_PORT,
database: process.env.AUTH_DATABASE_NAME,
user: process.env.AUTH_DATABASE_USER,
password: process.env.AUTH_DATABASE_PASSWORD,

});`

2.Check User and Password: Make sure that the user and password in your .env file match those used to create the PostgreSQL user.

3.Database Initialization: Sometimes, the PostgreSQL container might not initialize the user correctly. You can try connecting to the PostgreSQL container and manually checking the user credentials

4.Docker Networking: Ensure that your application is using the correct hostname. Since your containers are running in a Docker network, try using the service name postgres as the host instead of localhost

5.Check pg_hba.conf: The PostgreSQL pg_hba.conf file controls client authentication. You can access it inside the container and ensure it allows connections from your application:

docker exec -it postgres cat /var/lib/postgresql/data/pg_hba.conf

Ensure there is an entry like:

host    all             all             0.0.0.0/0            md5

6.Docker Logs: Check the logs of the PostgreSQL container for any hints
