What does your `$ELASTICSEARCH_HOST` var look like? `elasticsearch.host` should be a full URL, including schema (`http` or `https`). Example:
```auto
export ELASTICSEARCH_HOST=http://localhost
export ELASTICSEARCH_PORT=9200
```
then concatenating the two would give you a full URL:
`elasticsearch.host=${ELASTICSEARCH_HOST}:${ELASTICSEARCH_PORT}`
comes out as:
`elasticsearch.host=http://localhost:9200`

Hey @Irina_Truong , I changed it to elasticsearch.host=https://localhost:9200 and got the following error in response .
```auto

```
I can confirm elasticsearch is running and is kibana as well.

Ah. You get a different error! This is great. I also think my previous advice was wrong, you don't want to refer to `localhost`. If you are running both Elasticsearch and Enterprise Search in Docker, then you want elasticsearch.host setting to look like this - hostname `elasticsearch` corresponds to service name in `docker-compose`:
```auto
elasticsearch.host: http://elasticsearch:9200
```
However, if your Elasticsearch is running on `localhost` outside of docker, then you want the setting to look like this:
```auto
elasticsearch.host: http://host.docker.internal:9200
```
As far as I know, the `host.docker.internal` feature is available on Mac and Windows. On Linux you may need a workaround:
> **[Docker container to connect localhost of host](https://djangocas.dev/blog/docker-container-to-connect-localhost-of-host/#docker-for-linux)**
>
> Inside \*Docker\* container, want to connect service on \*localhost\* of host machine.
> There is a magic hostname \`host.docker.internal\` can be used inside Docker container
> to reach \*localhost\* of host machine.
Hope this helps.
