Hello. I have a cluster with 3 Elasticsearch master servers (7.17.6) on Windows 10. Here is my elasticsearch.yml for the first server (commented lines deleted, names and IPs edited):
```auto
cluster.name: MyCluster
node.name: MyMaster1
path.data: "D:\\Elastic\\Elasticsearch\\data"
path.logs: "D:\\Elastic\\Elasticsearch\\logs"
network.host: 10.0.0.1
discovery.seed_hosts:
- 10.0.0.2:9300
- 10.0.0.3:9300
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.verification_mode: none
xpack.security.transport.ssl.keystore.path: elastic-certificates.p12
xpack.security.transport.ssl.truststore.path: elastic-certificates.p12
xpack.security.http.ssl.enabled: true
xpack.security.http.ssl.keystore.path: elastic-certificates.p12
xpack.security.http.ssl.truststore.path: elastic-certificates.p12
```
Kibana (7.17.6) and Metricbeat (7.17.6) are also installed on MyMaster1. Here is metricbeat.yml:
```auto
metricbeat.config.modules:
path: ${path.config}/modules.d/*.yml
reload.enabled: false
setup.template.settings:
index.number_of_shards: 1
index.codec: best_compression
output.elasticsearch:

verification_mode: "none"
processors:

```
Testing config (host info removed):

Then (lines with same info as above removed):

```
I originally created the certificate files (CA, Elasticsearch nodes and Kibana) with a command like:
```auto
bin\elasticsearch-certutil cert --keep-ca-key --pem --in .\instances.yml --out .\CERT\certs.zip
```
The instances.yml file was like:
```auto
instances:
- name: 'MyMaster1'
dns: ['10.0.0.1']
- name: "MyMaster2"
dns: ['10.0.0.2']
- name: 'MyMaster3'
dns: ['10.0.0.3']
- name: 'MyKibana'
dns: ['10.0.0.1']
```
Later I switched to elastic-certificates.p12 files for each Elasticsearch server. I don't remember now which tool or command I used to create the .p12 files from the pre-existing node certificate files. I have just opened the CA certificate within the .p12 file and the stand-alone .crt PEM file originally created by certutil to compare them, and they have different properties. Is this expected or not? May this be the cause of the "certificate signed by unknown authority" error?
