Blob.download_to_filename does not work

[Menghetz]

I am having everytime my python scripts uses the blob.download_to_filename method.
I am running the fake-gcs-server using this command

docker run --rm -p 4443:4443 fsouza/fake-gcs-server -scheme http

Here below is my Python script

from google.auth.credentials import AnonymousCredentials
from google.cloud import storage
from pathlib import Path

client = storage.Client(
    credentials=AnonymousCredentials(),
    project="test",
    client_options={"api_endpoint": "http://127.0.0.1:4443"},
)
bucket = client.bucket("test-bucket")
# Create the bucket in the fake GCS server
if not bucket.exists():
    client.create_bucket("test-bucket")

# Upload all txt files from tests/data folder to the fake GCS server
data_folder = Path('tests/data')
txt_files = list(data_folder.glob('*.txt'))

for txt_file in txt_files:
    blob = bucket.blob(f'folder/{txt_file.name}')
    with open(txt_file, 'r') as f:
        blob.upload_from_string(f.read())
    print(f"Uploaded {txt_file.name} to fake GCS bucket.")

# List the Buckets
for bucket in client.list_buckets():
    print(f"Bucket: {bucket.name}\n")
    # List the Blobs in each Bucket
    for blob in bucket.list_blobs():
        print(f"Blob: {blob.name}")

        # Print the content of the Blob
        b = bucket.get_blob(blob.name)
        s = b.download_to_filename('test.json')
        print(f"Downloaded `{blob.name}")

And these are the execution logs

Uploaded file1.txt to fake GCS bucket.
Uploaded file2.txt to fake GCS bucket.
Bucket: test-bucket

Blob: folder/file1.txt

I can correctly upload files into the server, list the buckets and get blob info. But the code is stucked at download_to_filename

Here below is the error I am getting

requests.exceptions.ConnectionError: HTTPConnectionPool(host='0.0.0.0', port=4443): Max retries exceeded with url: /download/storage/v1/b/test-bucket/o/folder%2Ffile1.txt?alt=media (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x000002B43E8FA120>: Failed to establish a new connection: [WinError 10049] The requested address is not valid in its context'))

Any idea about what the error could be?

Can you share the server logs?
