Hi Bruce,

Are you able to regenerate the certificates? I would also recommend checking the location of the keystore in your configuration. The below resources might help:

1. [Filebeat vs elastic putput](https://discuss.elastic.co/t/filebeat-vs-elastic-putput/327506/9)
2. [SSL configuration assistance](https://discuss.elastic.co/t/ssl-configuration-assistance/304778/3)
