Puppet learning 0curl: (7) Failed connect to learning.puppetlabs.vm:8140; Connection refused

Trying the very first few commands from the tutorial of puppet and getting the error:

learning@hello: $ curl -k https://learning.puppetlabs.vm:8140/packages/current/install.bash | sudo bash

learning@hello: $


After searching some time over the net the solution is restart pe-puppetserver

root@learning: # service pe-puppetserver restart
Redirecting to /bin/systemctl restart pe-puppetserver.service

root@learning: #



Then run the command again and issue is all sorted now.
