Cant login into pgAdmin 4 with docker - docker

Question

I feel like its highly stupid question, but I just cant log into my pgAdmin.
My compose.yml file is
services:
back:
container_name: blog-django
build: ./blog-master
command: gunicorn blog.wsgi:application --bind 0.0.0.0:8000
expose:
- 8000
links:
- db
volumes:
- blog-django:/usr/src/app/
- blog-static:/usr/src/app/static
- blog-media:/usr/src/app/media
env_file: ./.env
depends_on:
db:
condition: service_healthy
nginx:
container_name: blog-nginx
build: ./nginx/
ports:
- "1337:80"
volumes:
- blog-static:/usr/src/app/static
- blog-media:/usr/src/app/media
links:
- back
depends_on:
- back
db:
container_name: db
image: postgres:14
restart: always
expose:
- "5432"
environment:
POSTGRES_DB: docker
POSTGRES_USER: docker
POSTGRES_PASSWORD: docker
ports:
- "5432:5432"
volumes:
- pgdata:/var/lib/postgresql/data/
healthcheck:
test: ["CMD-SHELL", "pg_isready -U docker"]
interval: 5s
timeout: 5s
retries: 5
pgadmin:
image: dpage/pgadmin4
container_name: pgadmin
restart: always
ports:
- "5050:80"
environment:
PGADMIN_DEFAULT_EMAIL: admin#admin.com
PGADMIN_DEFAULT_PASSWORD: root
volumes:
- pgadmin-data:/var/lib/pgadmin
depends_on:
- db
links:
- db
mailhog:
container_name: mailhog
image: mailhog/mailhog
#logging:
# driver: 'none' # disable saving logs
expose:
- 1025
ports:
- 1025:1025 # smtp server
- 8025:8025 # web ui
volumes:
blog-django:
blog-static:
blog-media:
pgdata:
pgadmin-data:
and my .env file is
DEBUG=1
SECRET_KEY='a key'
DJANGO_ALLOWED_HOSTS=localhost 127.0.0.1 [::1]
SQL_ENGINE=django.db.backends.postgresql
SQL_DATABASE=docker
SQL_USER=docker
SQL_PASSWORD=docker
SQL_HOST=db
SQL_PORT=5432
DATABASE=postgres
but with any username/email and password it keeps saying "wrong email/password". although if I login with "admin#admin.com" error is "Incorrect username or password" and with username it says "email/username is not valid"
I tried using admin#mailhog.local email so I can do password recovery, but again, "Incorrect username or password"
