Figured it out. So, the default generated config.yaml defines self_hostname as self_hostname: &self_hostname "localhost".

If you don’t have IPv6 enabled in your environment, requests will still resolve localhost to mean ::1 and not 127.0.0.1. Replacing localhost with 127.0.0.1 allows the node to start successfully.

I presume this would work fine on an environment with ipv6 enabled.

Thx! It worked for me.
