Adding PasswordAuthenticator to a Docker instance does not enable authentication

I have a docker compose file with a cassandra container. As default, I can manage the database anonymously because of AllowAllAuthenticator in cassandra.yaml, I want to have PasswordAuthenticator. That’s my docker compose:

cassandra:
    image: cassandra:4.1
    container_name:  "cassdb"
    ports:
      - 9042:9042
    volumes:
      - ./cassandra:/var/lib/cassandra
    environment:
      - CASSANDRA_CLUSTER_NAME=cassclus

I tried copying the file outside the container, editing it and sending it back and restarting container.

I have also tried to copy it outside the container, editing it and creating a volume with it in order to load it on docker compose up:

  - ./cassandra.yaml:/etc/cassandra/cassandra.yaml

In both cases, I get that error whenever doing cqlsh or cqlsh -u cassandra -p cassandra from inside the container (which I didn’t have before):

Connection error: ('Unable to connect to any servers', 
  {'127.0.0.1:9042': ConnectionRefusedError(111, 
  "Tried connecting to [('127.0.0.1', 9042)]. 
  Last error: Connection refused")})

I have even tried to add the container with the volume but doing no change to the .yaml I have imported from the container, so I don’t think it is related with the PasswordAuthenticator value itself, but with the whole file.

My host machine is a Windows and I am editing the file with Visual Studio Code, I don’t know if that may have anything to do.
