Remote loads from MetaAlmanac hang forever in Python

[Chris]

Bug report

Describe the bug

In Python, the MetaAlmanac cannot successfully load the default remote files. It just hangs forever.

To Reproduce

data_path = Path(__file__).parent.joinpath("..", "..", "data", "default_meta.dhall")
meta = MetaAlmanac(str(data_path))
print(meta)
# Process the files to be loaded
ctx = meta.process() # --> This line will hang forever

Expected behavior

It should just download the files and get on with it, as it does in Rust.

Code to reproduce the issue

Cf. above

Platform

Linux and Github CI all platforms.

Additional context

None
