[MacOS] socket.gaierror: [Errno 8] nodename nor servname provided, or not known

[GaetanLepage]

When packaging the latest version (5.2.2) on nixpkgs, I noticed that the following tests were failing on MacOS (both x86_64 and aarch64) while they work fine on linux:

ERROR tests/test_0692_fsspec_writing.py::test_fsspec_writing_http - socket.gaierror: [Errno 8] nodename nor servname provided, or not known
FAILED tests/test_0692_fsspec_reading.py::test_open_fsspec_ssh[FSSpecSource] - socket.gaierror: [Errno 8] nodename nor servname provided, or not known

Here is the full stacktrace for one of them:
