I'm not able to get kibana to present username password continuously shows:

10.141.0.171:5601  
Kibana server is not ready yet.

kibana.log shows:

"ecs":{"version":"8.4.0"},"@timestamp":"2022-09-01T13:03:37.022-04:00","message":"Unable to retrieve version information from Elasticsearch nodes. socket hang up - Local: 10.141.0.171:53038, Remote: 10.141.0.170:9200","log":{"level":"ERROR","logger":"elasticsearch-service"},"process":{"pid":900},"trace":{"id":"3ade4c23f557a2ddd0ff197d27775d16"},"transaction":{"id":"dc0af279d635b759"}}

I'm able to curl from the kibana server using the kibana\_system user.  
I copied the elastic cert (/etc/elasticsearch/certs/http\_ca.crt) over to the kibana server (/etc/kibana/certs)

[root@rbdckibana01 kibana]# curl --cacert /etc/kibana/certs/http\_ca.crt -u kibana\_system [https://10.141.0.170:9200](https://10.141.0.170:9200)  
Enter host password for user 'kibana\_system':

```auto

  "name" : "rbdcelastic01",
  "cluster_name" : "rbdc-elk-stack",
  "cluster_uuid" : "gyBRmaH2SLCDle39ZSCdTQ",

    "minimum_index_compatibility_version" : "7.0.0"
  },
  "tagline" : "You Know, for Search"
}

```

Any thoughts on what could be causing and how to fix?

When I change the xpack.security.enabled:true to false I'm able to get in.

Your `elasticsearch.yml` has SSL enabled for clients:

```auto
xpack.security.http.ssl:
  enabled: true
  keystore.path: certs/http.p12

```

So, if you enable this you need to use **HTTPS** , but your `kibana.yml` is configured to use **HTTP**.

```auto
elasticsearch.hosts: ["http://10.141.0.170:9200"]

```

Try to change it to **https**.

You are a godsend! That was it... So simple, I don't know why I didn't catch that 🤦‍♂️...
