Solved: Reload failed because retrieve_conf encountered an error: 1

I’m running freepbx 13, this is an upgrade from the original freepbx 12 distro. I’ve just updated some modules and clicked ‘apply config’ and it gives this error:

Reload failed because retrieve_conf encountered an error: 1
exit: 1
Unable to connect to remote asterisk (does /var/run/asterisk/asterisk.ctl exist?)
Exception: Unable to connect to Asterisk through the CLI in file /var/lib/asterisk/bin/retrieve_conf on line 43
Stack trace:
1. Exception->() /var/lib/asterisk/bin/retrieve_conf:43

I’ve been trawling google and this forum but so far can’t find a solution.

ps -A | grep “asterisk”

thanks for your response andrew, I solved it with:
fwconsole restart.
I tried loads of different things before coming across this simple command.
