Hi @Bewinxed, really sorry for the delay on this. It looks like this is just a connection issue locally for you, though. Please let me know if this isn't the case? Thanks!

Hi @Bewinxed, closing as stale but please let me know if you still need help on this.

This appears to be a race condition in the underlying systems that can be worked around by immediately retrying: https://github.com/urllib3/urllib3/issues/951
