SOLUTION: added local chef server to no_proxy

I'm attempting to go through the learn.chef.io tutorial "Install a Chef Server".

I'm not sure what to do with all these ruby errors

$ knife ssl fetch
WARNING: Certificates from chef-server.test will be fetched and placed in your trusted_cert
directory (c:\users\212336986\documents\training\learn-chef.chef\trusted_certs).

Knife has no means to verify these are the correct certificates. You should
verify the authenticity of these certificates after downloading.

You need to add these certificates as trusted else sometimes it doesn’t allow to connect to chef server.
