Run Puppet not working on GUI

Hi everybody! I've followed the instructions at
Foreman :: Manual . I'm trying to
use the puppet_proxy_ssh to run puppet through the GUI. When i click "Run
Puppet", it shows a success message, but nothing happens on client side. If
i run the agent from foreman-proxy host (Puppet server) through SSH using
root or foreman-proxy user, everything is OK. Any tips?

Thanks in advance.
