Hi, please format your codes and errors under preformatted text `</>` or `backticks (```) `as it is hard to read otherwise.

1. When you start the service, did you see any errors in log?
2. To test certs using curl, you can use  
` curl --cacert /path/to/ca.crt -u elastic 'https://xxx:9200/_cat/nodes?v'`
3. To convert p12 to pem, you can use `openssl` for example see link below  
[Make .p12 to .pem for kibana](https://discuss.elastic.co/t/make-p12-to-pem-for-kibana/183231/6)

Do share the outcome from 1 and 2.
