Hi Team,
I have configure EFK with xpack enabled. I was able to configure kibana and fluent-bit with same ssl certificates. Now i am trying to configure metricbeat in my cluster.
It failed to pass readiness probe check.
I createdCA certificate without any dns name /elasticsearch-certutil ca and generate certficates. I converteed PKC#12 keystore to PEM format. I was able to use same certificate for kibana and fluent-bit ( tls.verify Off). I am not abel to use same certificate with metricbeat.
```auto
sh-4.2# metricbeat test output
elasticsearch: https://elasticsearch-master:9200...
