BIND9 Plugin Always Reconnecting

I am not sure this is a bug or not, but after i install Bind9 then start the service.
on the website Interfaces, i click BIND9 from Software Tab. and it seems Anjeti Service has been crash or stop, because it show Reconnecting and no process taken.
i have trying to figure the logs, but i can't find logs for Ajenti because i am new on Ajenti.
