Call to Firestore getting timed out from the docker container.

Start with src/async_client_messaging_app/settings/firebase_manager.py at initialize_firebase and the doc_ref.set call shown in the traceback. Compare the Firestore and OAuth requests from the local environment with those from the Docker container, including the container networking setup. Done means identifying a reproducible cause for the DeadlineExceeded error and documenting a verified fix.

I'm facing an issue while creating a single record in the Google Firestore document from the docker, whereas the same code works fine in my local.

Below is the error I am getting:

Any leads for fixing this would be appreciated?
