Elasticsearch.yml config to solve the "Upgrade Required Your version of Elasticsearch is too old. Kibana requires Elasticsearch 0.90.9 or above." problem

Elastic Stack Elasticsearch
1

Hi ! I want to access to Kibana by 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. 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?
