Did not receive certifcate
On a couple of nodes I am getting an entry like this in the logs:
Jul 16 09:08:36 database puppet-agent: Did not receive certificate
From another post on StackOverflow I saw that sometimes this is due to the /etc/hosts not being correctly populated. In no cases has this fixed the issue for me.
It is odd that the hostname showed in the logs is an old hostname for each server. However each server had their certificate re-generated after each had their hostnames changed. The hostnames were also correctly updated in both /etc/hosts & /etc/sysconfig/network.
A manual Puppet run via a puppet agent -t runs fine, it's only when the daemon tries to call to the master that this error is produced.
