Error when apply config on admin?

Hello

I have installer frepbx using the cento os6.5 tuto

on the admin page, when i clik on the button “apply config” i get this error :

exit: 1

[FATAL] Unable to connect to Asterisk Manager from /var/lib/asterisk/bin/retrieve_conf, aborting

Someone know what is the issue ?

Thank you

As says “can’t connect to Asterisk Manager”. Meaning what you have set as your Asterisk Manager settings in advanced settings don’t match what’s in /etc/asterisk/manager.conf
