Finally got this with my own neuro client, not the one running on CircleCI:

$ n status airflow-inference

Reproduced on Mac OS with the latest neuro-cli update

It has been fixed by @asvetlov in #1497.
https://github.com/neuromation/platform-client-python/blob/dfe74a9614732a02ffdd1a8652db37dedc23e94a/neuromation/api/core.py#L171-L178

We do not know the root cause yet, but at least it is no longer manifested to users. Just wait the next release.

Would be nice to fix the root cause, but it is not critical now.

The root case is described (and fixed) by https://bugs.python.org/issue33786
