[Bro] Brownian and Ubuntu 16.04

[Hamid Reza Ghaeini]

Hi.
I configured the Brownian based on your instructions and the following link:
http://www.hyperionavenue.com/?p=692

My configurations are:
Elasticsearch 2.3.3
Bro 2.4.1
Ubuntu 16.04 LTS

I followed the procedure and it works on Ubuntu 14.04.
I wondering why it is not working in the new version of Ubuntu.
I did this for testing the elasticsearch.

curl 'localhost:9200/_cat/indices?v' | grep bro
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 270 100 270 0 0 4302 0 --:--:-- --:--:-- --:--:-- 4354
yellow open @bro-meta 5 1 1 11 4.8kb 4.8kb
yellow open bro-201605312100 5 1 0 0 795b 795b

But it looks that elasticsearch is working fine.
But the brownian show this error:
Error! Could not connect to server - please check ELASTICSEARCH_SERVER in
settings.py

Could you please help me to solve this problem?

Thanks.
