Hello,

I'm using Kibana 3.0.1 and ES 1.7.3.  
**Everything worked fine yesterday,** but today I got the following error on kibana:  
'Could not contact Elasticsearch at [http://IP:80](http://IP:80). please ensure that elasticsearch is reachable from your system.

My kibana.yml has this config:  
`elasticsearch: "http://"+window.location.hostname+":80"`

My nginx config is taken from here: [https://gist.githubusercontent.com/thisismitch/2205786838a6a5d61f55/raw/f91e06198a7c455925f6e3099e3ea7c186d0b263/nginx.conf](https://gist.githubusercontent.com/thisismitch/2205786838a6a5d61f55/raw/f91e06198a7c455925f6e3099e3ea7c186d0b263/nginx.conf)

How can I solve this problem?  
Thanks
