Unable to download cache files

[VictorSeven]

Describe the bug
When I try to download the cache files as described in the Data Access Tutorial, I am unable to do so. In particular,

1. probes.csv and sessions.csv would be downloaded without a problem, but the notebook cell continues to execute, apparently indefinitely until Ctrl+C
2. channels.csv and units.csv would not even be downloaded.

I just saw issue #1696 and I think that it might be that they take an extraordinarily long time, but this is unreasonable and does not allow me to work with the files. Also, contrary to that issue, in my case, two files were not downloaded.

To Reproduce

I just installed the AllenSDK right now and used the following code (almost identical to the tutorial, linked above)

import os
import shutil
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
from pathlib import Path

from allensdk.brain_observatory.ecephys.ecephys_project_cache import EcephysProjectCache

#new cell
data_dir = "./data"
manifest_path = os.path.join(data_dir, "manifest.json")
cache = EcephysProjectCache.from_warehouse(manifest=manifest_path) 

#new cell 
session = cache.get_session_table()
#or any other of the 4 functions

Expected behavior
I would expect the file to be downloaded and return the control to the notebook immediately.

Actual Behavior
Two files were downloaded, but control did not return. Another two files were not even downloaded.

Environment (please complete the following information):

• OS: Ubuntu 20.04
• Python: 3.11
• AllenSDK: 2.16.2

Additional context
I believe my problem is related or identical to #1696
