Question

This is my configues: https://gist.github.com/farzinh/b50312ca0523fb37ec846251a7671cb3 and here is docker-compose logs that shows

error:

....
django/db/backends/postgresql/base.py", line 187, in get_new_connection
connection = Database.connect(**conn_params)
File "/usr/local/lib/python3.9/site-packages/psycopg2/__init__.py", line 127, in connect
conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
django.db.utils.OperationalError: could not connect to server: Host is unreachable
Is the server running on host "db" (192.168.96.2) and accepting
TCP/IP connections on port 5432?

I checked every and each solution that I could found, but none of them works and I still have this error
