Hi everyone,

I start elasticsearch and check status, it's running. But when I use curl to access, I receive an message: Connection refused.  
Here is my code when I check in command line:

```
                 root@hieu: service elasticsearch start
                 root@hieu: systemctl -l status elasticsearch
            ● elasticsearch.service - Elasticsearch

            curl: (7) Failed to connect to 127.0.0.1 port 9200: Connection refused 

```

Check netstat:

`root@hieu-Latitude-E6420:/home/hieu# netstat -tulnp | grep 9200`

and it's not respond anything.

In my elasticsearch.yml:

```
    network.host: localhost
    http.port: 9200

```

Thanks.

Thanks for asked, this is what I saw in elasticsearch.log:

```

That's probably why. Could you share the full log please ?

And explain what you exactly did. Like did you install a new version...

</div>

based on the exception here, it looks like you upgraded to elasticsearch version 7, and then downgraded to version 6. Downgrades are not possible.

I use this links to install  
([https://linuxize.com/post/how-to-install-elasticsearch-on-ubuntu-18-04/](https://linuxize.com/post/how-to-install-elasticsearch-on-ubuntu-18-04/))

install java8 -\> apt update -\> Import the repository’s GPG -\> add the Elasticsearch repository to the system -\> update -\> install elasticsearch

I also set path for JAVA\_HOME:

```
root@hieu-Latitude-E6420:/etc/apt/sources.list.d# echo $JAVA_HOME
/usr/lib/jvm/open-jdk

```

But still got this warning:

`warning: Falling back to java on path. This behavior is deprecated. Specify JAVA_HOME`

Do you think I should remove and install new version?  
Currently, I'm use elasticsearch version 6.7.1

I used: `apt-get remove --purge elasticsearch` to remove version before and install ver 6.7.1 . And I following this tutorial to install:

Thank two guys, I just change $JAVA\_HOME from`/usr/lib/jvm/java` to `/usr/lib/jvm/java-8-openjdk-amd64` (I check list of file in jvm folder and saw `java-8-openjdk-amd64` instead of `java` ), then restart. I don't know what's wrong but it's work now.

Thank for your help again!
