hi,  
I've been trying to simulate a Kibana to Elastic Connection. (As per the [Link](https://discuss.elastic.co/t/warning-migrations-unable-to-connect-to-elasticsearch-error-request-timeout-after-30000ms/215472) it was related to Kibana OSS, but I tried both Kibana and Kibana-oss, but still no luck.)

> ./bin/kibana --version  
> 7.6.2

cat custom/config/kibana.yml

> ```

and Starting using  
` ./bin/kibana -c custom/config/kibana.yml`

```

```

I can reach the ElasticURL correctly from the Kibana installed location using curl.

Not sure why its so hard to setup a simple elastic/kibana combination ☹

Hello,

Where did you get that `-c` param for /bin/kibana? I don't remember that ever being available. Kibana should only load settings from the /config/kibana.yml file

Kibana can load from external config using -c

Configuration at Elasticsearch.yml is

```auto
# ======================== Elasticsearch Custom Configuration =========================

## Modify this and make it dynamic later##
cluster.name: "my-cluster"
network.host: 0.0.0.0
discovery.seed_hosts: []

## X-Pack settings
## see https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-xpack.html
#
xpack.license.self_generated.type: trial
xpack.security.enabled: true
xpack.monitoring.collection.enabled: true

```

The only error at ElasticSearch end is:

```auto

At last found the problem !!

Put in following setting in elasticsearch.yml and it worked.

```auto
network.host: 0.0.0.0
discovery.type: single-node

```

That config setting only works for development version of Kibana (when you run it from source). Changing that to 0.0.0.0 worked because the default kibana.yml looks for elasticsearch on localhost (or 0.0.0.0).

</div>

oh. I didn't run from source. I ran from the binary and it worked

I could put `network.host` any value within the network segment and it works. (theoritically it was working before as well). The key setting was `single-node` for development/basic purposes.
