Nifi on start , tries to launch a bootstrap process which tries to connect to ports available on the server(host). In your case, it was trying to connect to port(42511) in first instance of startup and port(34170) in second instance of start up. But ports seems to have blocked, hence you are getting connection refused. Please check your firewall settings.
