Hello,
I have recently installed elasticsearch 7.2 on my Ubuntu 18.04. Initially elasticsearch service was not starting due to some Java issue, Once I installed java and set JAVA\_HOME, service started working fine and is showing Active running. However, when I run curl localhost:9200, it gives me error connection refused. I have checked elasticsearch.yml file and made entry in **network.host: [_host_,_site_]**. Still no good. Please assist.

Hi,
Now its seems elasticsearch is working, when i changed host setting to 127.0.0.1, I am able to see curl results. But still when i change it to **[_local_,site\_]**. it stops working. I have already check firewall etc.

These are the logs after I commented out **network.host** option in elasticsearch.yml. Now i can access it locally not remotely.

We need the logs when it fails.
