Puppet fails with Error 500 on SERVER: Server Error: Failed when searching for node client.example.com

Solution Verified - Updated -

Environment

  • Red Hat Satellite 6.x
  • Red Hat Enterprise Linux

Issue

  • # puppet agent -t fails with:
Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Failed when searching for node client.example.com: Failed to find client.example.com via exec: Execution of '/etc/puppetlabs/puppet/node.rb client.example.com' returned 1

Resolution

  • Check the entries for ssl_ca, ssl_cert, ssl_key in /etc/puppetlabs/puppet/foreman.yaml on the satellite server. The file should have entries as:
---
:url: "https://satellite.example.com"
:ssl_ca: "/etc/pki/katello/puppet/puppet_client_ca.crt"
:ssl_cert: "/etc/pki/katello/puppet/puppet_client.crt"
:ssl_key: "/etc/pki/katello/puppet/puppet_client.key"
:user: ""
:password: ""
:puppetdir: "/opt/puppetlabs/server/data/puppetserver"
:puppetuser: "puppet"
:facts: true
:timeout: 60
:report_timeout: 60
:threads: null

  • Restart the katello service after making correct entries:
    # katello-service restart

  • Regenerate puppet certs and sign them:
    On the client run # puppet agent -tv.

  • The issue can also be due to incorrect Host Group Parameter or Host Parameters set on the client.
    Login to satellite web ui > Hosts > All Hosts > search and click on the client host > Edit > Parameters tab:
    Delete the Host Group Parameter or Host Parameters set.
