[rabbitmq-discuss] rabbitmq nodedown error

[pi]

I tried to stop and start rabbitmq server but keep getting the nodedown 
error as shown below.
I read that we should synchronise Erlang Cookies but how should that be 
done?
running the line below shows cookie that's different from cookie hash, does 
it mean that's the cause? 
sudo cat .erlang.cookie

me at myserver:~$ sudo rabbitmqctl stop
Stopping and halting node rabbit at myserver ...
