Search Guard certificate error

I am running Elasticsearch 6.1.1 and Search Guard 6.1. I have created certificates and keys and edited the elasticsearch.yml file. I am getting the error below. The key is in pkcs8 format. I saw another post about that. This error in the logs happens when I try to start the elasticsearch service. Any help would be greatly appreciated.

search guard config in elasticsearch.yml (The password is the password used with the creation of the cert.)
