Hello,  
I am brand new to ELK, i try to make a test environnement at home.

I just set up a elastic cluster, it works fine. All my three noeuds connetcts to each other.  
I installed a kibana server, and i follow the guide  
[here](https://www.elastic.co/guide/en/elasticsearch/reference/8.0/security-basic-setup-https.html#encrypt-http-communication)

it provides 3 http.p12 files for my 3 noeuds and 1 elasticsearch-ca.pem for my kibana.

- For elastic noeuds

i upload the http.p12 files in the /etc/elasticsearch/certs/ directory on each elastic noeuds and i make sure that the system recognize the password with that command : /usr/share/elasticsearch/bin/elasticsearch-keystore add pack.security.http.ssl.keystore.secure\_password

- For kibana

i upload the elasticsearch-ca.pem file in the /etc/kibana/certs/ directory , and mi kibana.yml file look like this

```auto
**server.host: "192.168.208.140"**
**elasticsearch.hosts: ["https://192.168.208.135:9200", "https://192.168.208.136:9200", "https://192.168.208.134:9200"]**
**elasticsearch.ssl.certificateAuthorities: ["/etc/kibana/certs/elasticsearch-ca.pem"]**
 **# Enables you to specify a file where Kibana stores log output.**
 **logging:**
 **appenders:**
 **file:**
 **type: file**
 **fileName: /var/log/kibana/kibana.log**
 **layout:**
 **type: json**
 **root:**
 **appenders:**
 **- default**
 **- file**
 **pid.file: /run/kibana/kibana.pid**

```

I open 9200 port on all noeuds

After all this when i restart all service (kibana and elastic) on my kibana server i get this error 🙂

Welcome to our community! 😃

Can you curl to Elasticsearch without any errors?  
What does your kibana.yml look like?
