Hi Everyone, I try to install Elasticsearch8.2.2 and Kibana8.2.2 on the one ubuntu20.04 virtual machine. I installed and configured Elasticsearch8.2.2 and get accessed from my local browser successfully. As below picture. ![image](https://us1.discourse-cdn.com/elastic/original/3X/9/8/980d072b03d83bb055092aa2ea4a8027c02de81b.png) I also installed and configured Kibana8.2.2. But when I try to get access from my local browser. Browser always say` Kibana server is not ready yet.` ![image](https://us1.discourse-cdn.com/elastic/original/3X/b/9/b998284ecac59686ab380887bb337f95efc5f3bc.png) > root@el1# **sudo systemctl status kibana.service** > Jun 05 11:19:55 elastic1 kibana[17804]: [2022-06-05T11:19:55.411+00:00][ERROR][elasticsearch-service] Unable to retrieve version information from Elasticsearch nodes.\> > root@el1# **journalctl -f -u kibana.service** > un 05 11:19:55 elastic1 kibana[17804]: [2022-06-05T11:19:55.411+00:00][ERROR][elasticsearch-service] Unable to retrieve version information from Elasticsearch nodes. self signed certificate in certificate chain > Jun 05 11:19:58 elastic1 kibana[17804]: [2022-06-05T11:19:58.607+00:00][INFO][plugins.screenshotting.chromium] Browser executable: /usr/share/kibana/x-pack/plugins/screenshotting/chromium/headless\_shell-linux\_x64/headless\_shell root@el1# **sudo nano /etc/elasticsearch/elasticsearch.yml** ```auto path.data: /var/lib/elasticsearch path.logs: /var/log/elasticsearch xpack.security.enabled: true xpack.security.enrollment.enabled: true xpack.security.http.ssl: enabled: true keystore.path: certs/http.p12 xpack.security.transport.ssl: enabled: true verification_mode: certificate keystore.path: certs/transport.p12 truststore.path: certs/transport.p12 cluster.initial_master_nodes: ["elastic1"] cluster.name: elastic node.name: elastic1 network.host: 192.168.216.142 ``` root@el1# **sudo nano /etc/kibana/kibana.yml** ```auto server.port: 5601 server.host: "192.168.216.142" elasticsearch.hosts: ["https://192.168.216.142:9200"] elasticsearch.username: "kibana_system" elasticsearch.password: "B4CRasddasdasGBXzTI" # 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 ``` ---

Hi @HKN_MZ As the error says > Unable to retrieve version information from Elasticsearch nodes. self signed certificate in certificate chain You need to provide the self signed CA for elasticsearch to Kibana in `kibana.yml` `elasticsearch.ssl.certificateAuthorities: "/path/cert.ca"` > **[Configure Kibana | Kibana Guide \[8.11\] | Elastic](https://www.elastic.co/guide/en/kibana/current/settings.html)** You can test by setting `elasticsearch.ssl.verificationMode: "none"` But that is not recommended for production. ---

Thank's for your repply, You are right when I added this code `elasticsearch.ssl.verificationMode: "none"` in kibana.yml. Problem is fixed. I checked your shared document but I didn't figure out Where is `cert.ca` file? or should I create this file? ---

It depends on how you generated your certificates. Did you just use the default steps when you installed elasticseaech or is it a certificate from your company or are you created them yourself. ---

I fixed the problem and I wrote an [article](https://hakanmazi123.medium.com/online-installation-elasticsearch-and-kibana-to-ubuntu-97ca71d869e2) about it. ---

Nice! That Works... Turns out you don't need to do that if you use [the enrollment token method](https://www.elastic.co/guide/en/elasticsearch/reference/current/configuring-stack-security.html#stack-start-with-security) ... which is just a shortcut to what you did... Glad you got it working... it was much harder in 7.x why I also wrote a [How To](https://github.com/bvader/howtos/tree/master/basic-security-elasticsearch)
