I hope you do not have an unsecured cluster exposed to the internet. Have you verified you do not have any firewall rules preventing you to access the host you are querying? ---

I was unclear probably. I can't tell without seeing your `elasticsearch.yml` file. Copy its content here unmodified and apply on it the formatting tool (`` icon) or share the raw file on [gist.github.com](http://gist.github.com). ---
