Hi , I am beginner to elastic search and using HEAD plugin as UI interface.I had worked with ES version of 1.3.2 ,working fine and now I had upgraded ES to version 2.3.2 both the server and client pc. I mean that I have installed ES at domain e.g. [www.example.com](http://www.example.com) and accessing it in my local with HEAD plugin as [http://localhost:9200/\_plugin/head](http://localhost:9200/_plugin/head). Now when I try to access ES with browser e.g. [www.example.com/\_stats](http://www.example.com/_stats) than it's working fine , but when I try to connect it with HEAD plugin than it shows 200 response and gives CORS related error on console. I have tried all configuration of elasticsearch.yml at my local by searching but it's doesn't seems to be work for me. I have attached images related to that.

Thanks. ---

Have you tried to uninstall the plugin and reinstall. I think i had similar issues when going from 1.x to 2.x and the remove and reinstall plugin worked. Also I would investigate the Kopf and HQ plugins. Kopf is the newer head plugin and in my opinion a much improved interface vs head. ---

Thanks for the reply. I have reinstalled head plugin and also reinstalled whole ES. But it does not work for me. I have also used kopf and HQ but head is a very clean ui that's why I prefer it. Anyway, I need to know something that Does head plugin is supported with newer version ? And What about CORS settings it is added either at client ES or Server ES or Both? Thanks. ---

It is my understanding that CORs is not required on 2.x. I am not sure if all 2.x or just later versions. I commented out CORS lines out of my configs after upgrading to 2.3.1 ---

My problem has been resolved by adding these lines and I am able to connect other nodes by HEAD plugin. network.host: 0.0.0.0 http.port: 9200 http.cors.enabled: true http.cors.allow-origin: "\*" ---
