Postgresql – Why my RDS instance is not connecting with my Django project?

I’m trying to connect my Django Project with a RDS instance with Postgre engine

It’s a free tier option

The instance is running normally with no problems

I’ve set my Inbound Rule to allow Postgre connection with my IP

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'angtradingdatabase',
        'USER': 'vitor',
        'PASSWORD': 'xxxxxx',
        'HOST': 'angtradingdatabase.xxxxxxx.us-east-2.rds.amazonaws.com',
        'PORT': '5432',
    }
}

But I’m receiving this error when I try to run the ‘python manage.py runserver’ code

django.db.utils.OperationalError: connection to server at "angtradingdatabase.cbe1o6n4gvvs.us-east-2.rds.amazonaws.com" (18.117.34.123), port 5432 failed: FATAL: database "angtradingdatabase" does not exist

The name of my database is angtradingdatabase as you can see in the picture, what is causing this problem??
