Answer 1

As the error message says:
Failed to open TCP connection to puppet:8140 (getaddrinfo: Name or service not known)
It cannot find the host puppet.
If you add that to /etc/hosts on your client and server, it should work:
192.168.64.14 puppet

Answer 2

If you run puppet agent -t as a non-root user, Puppet creates a configuration folder structure under ~/.puppetlabs and ignores /etc/puppetlabs/puppet/* (source: https://puppet.com/docs/puppet/latest/dirs_confdir.html, you can pick your version from the drop-down if you're not using the latest)
If you can, try running as root (sudo -i first, then run puppet agent -t) or try with sudo (which does not work for me, but may for you).

Answer 3

check if you open port 8140.
telnet puppet-server 8140
