I followed the installation instructions provided in the README.md

I am using python=3.10 and I have a Mac M1

Hi @filopedraz,

This seems to be a macOS compatibility issue. Please run the health monitor in Docker or on a Linux machine until it's fixed.

For the record: I've met the same error on Linux as well, but it's very rare (happened once in a few months during a routine state update on http://health.petals.dev). This seems to be a hivemind.DHT bug that is worth deeper investigation.
