Error on puppet master

[pufferfish]

Hi, i'm quite new to puppet software. I'm trying to figure out weird error on my servers.

error logs below

------------------------

[root@puffer clientbucket]# puppet agent -t --noop

Warning: Unable to fetch my node definition, but the agent run will continue:

Warning: Error 403 on SERVER: Forbidden request: puffer.puppetlabs.vm(127.0.1.1) access to /node/puffer.puppetlabs.vm [find] authenticated  at :55
