[FreeTDS][SQL Server]Login failed for user - django

Question

I am developing on a windows and trying to run the Django application in Linux container with Gunicorn and Nginx to deploy it to Linux machine in production.
I mostly used this Connect docker python to SQL server with pyodbc post as a guide but I think I have tried every solution found online about this error.
If I ping DB server from container it gets connected so the port 1433 is open and everything should be good to go. But for some reason I'm getting error django.db.utils.ProgrammingError: ('42000', "[42000] [FreeTDS][SQL Server]Login failed for user
Django settings.py

Answer 1

I finally solved it myself. Had to add port 1433 to nginx in .yml file.
Like this
nginx:
image: nginx:1.13
ports:
- 8000:80
- 1433:1433
volumes:
- ./config/nginx/conf.d:/etc/nginx/conf.d
- /static:/static
depends_on:
- djangoapp
networks: # <-- here
- nginx_network
