Hi ! I want to access to Kibana by [http://IP:80](http://IP:80).  
Nevertheless when I visit the pageI obtain these errors\>

> "\> Upgrade Required Your version of Elasticsearch is too old. Kibana requires Elasticsearch 0.90.9 or above."

> "Error Could not reach [http://localhost:80/\_nodes](http://localhost:80/_nodes). If you are using a proxy, ensure it is configured correctly"

I have been looking up these problems on the internet and I have included these lines without success...

```
"http.cors.enabled: true
http.cors.allow-origin: http://localhost:80
"  

```

My Elasticsearch version is in fact 0.90.9.

What could I do?  
please help me

Any reason you are on such an old version?
