How did you create the user certificate?
You can test it using curl:

  curl --key /path/to/key --cert /path/to/cert https://localhost:9200/

Client-mode is not a valid option for the elasticsearch-http() driver, so
don't use it (it was an option to the java elastic dest).

Again, test the client certificate with curl. My guess is that you generated
a node certificate instead of a client certificate.
