Puppet agent : SSL_connect Error - Certificate verify failed or CRL is not yet valid

What to do if puppet agent is reporting following errors:

• SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed: [CRL is not yet valid for /CN=puppetmaster]
• Failed to generate additional resources using 'eval_generate': SSL_connect
• Could not retrieve catalog from remote server: SSL_connect 
• Could not send report: SSL_connect

Try 1: Recreate SLL certificate

- Compare  /etc/puppetlabs/puppet/puppet.conf of host with another working system and fix any discrepancy
- Run puppet agent
 puppet agent -tv

Try-2 : Recreate certificate
- Delete certificate from host

find /etc/puppetlabs/puppet/ssl -type f
find /etc/puppetlabs/puppet/ssl -type f -exec rm -f {} \;

- Delete certificte from puppet CA server

 puppet cert clean host-fqdn-name

- Run puppet agent

puppet agent -t

- Sign client certificate on puppet CA Server

puppet sign cert host-fqdn-name

Try-3: Most interesting one ! Sync your host time with same ntp time source as your puppet master

service ntp stop
ntpdate -s time.nist.gov 
service ntp start
puppet agent -t
