Hi Community.

I am following the instructions in this tutorial -- Start a multi-node cluster with Docker:

> **[Install Elasticsearch with Docker | Elasticsearch Guide \[8.6\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html)**

I could access Elasticsearch by using this command "**curl --cacert ca.crt -u elastic:rogerfan [https://localhost:9200](https://localhost:9200)**" with the ca.crt file under "/ **usr/share/elasticsearch/config/certs/ca/ca.crt**" either from the docker container or the host.

However, when I changed the **localhost** to its actual IP **192.168.xxx.xxx** , it shows:

[root@localhost ~]# curl --cacert certs/ca/ca.crt [https://192.168.39.12:9200](https://192.168.39.12:9200)  
curl: (51) Unable to communicate securely with peer: requested domain name does not match the server's certificate.

I wonder if this is caused by the ca-certificates, I tried to find the location of http\_ca.crt but just ca.crt was found... So I am not quite sure what is the reason and how can I resolve it.

Thanks

Hi  
After changing the instance.yml file into this:  
elasticsearch@d407cef250af:~/config/certs$ cat instances.yml  
instances:

- name: es01  
dns:
  - es01
  - localhost  
ip:
  - 127.0.0.1
  - 192.168.39.12

- name: es02  
dns:
  - es02
  - localhost  
ip:
  - 127.0.0.1
  - 192.168.39.12

- name: es03  
dns:
  - es03
  - localhost  
ip:
  - 127.0.0.1
  - 192.168.39.12

I could use ca.crt to access [https://192.168.39.12:9200](https://192.168.39.12:9200) by **"curl --cacert certs/ca/ca.crt [https://192.168.39.12:9200](https://192.168.39.12:9200/)"**

But am I doing the right thing？
