Unable to connect to remote asterisk

Hey,

== Parsing ‘/etc/asterisk/asterisk.conf’: == Found
== Parsing ‘/etc/asterisk/extconfig.conf’: == Found
Unable to connect to remote asterisk (does /var/run/asterisk.ctl exist?)

I did see the asterisk.ctl in /var/run and also have given chown option for asterisk.ctl file and chmod 777 for var/run.

I checked the etc/default where RUNASTERISK= yes option.

/etc/asterisk/asterisk.conf

astrundir = /var/run

It was working perfectly well few days back but now I’m unable to connect remotely, why?

Help me, please!
