Elastic Stack Kibana

Hi,

I am not able to connect to my elasticsearch instance from kibana instance. Both are on AWS EC2.
Getting this error:

Error: Unknown error while connecting to Elasticsearch

Can you connect to ES ok - curl IP:9200?

Yeah..!!
Anyway I solved the problem. Not exactly solved it but downgraded the version of kibana and it worked like a charm. 4.1.2->4.1.1

I guess its a bug in Kibana latest version.

Unlikely, otherwise I'd have the same problem :wink:

If its working for you then it should work for me too. It cannot be connection problem as firewall is off on both the machines and the both belong to the same subnet. In my post I have mentioned my config file. Is something wrong with it?

Looks ok from what I can see.
