I'm getting the following error upon startup and I'm not sure how to get rid of them. Any quick thoughts?

You haven't configured a certificate and key for `transport.ssl`.  
You must set :

- `xpack.security.transport.ssl.keystore.path`, _OR_
- **both** `xpack.security.transport.ssl.certificate` and `xpack.security.transport.ssl.key`
