Rundeck Rundeck Development

I'm attempting a command over SSH:

ssh USER@HOSTNAME "uname -a"

I'm getting permission denied errors.

I have keys setup between the rundeck host and the remote server. I can terminal ssh between machines without issue and without a password.

Rundeck appears to be able to do this intermittently. I notice I am usually able to run the command successfully with rundeck so after bouncing the rundeck application, but after several attempts (or a certain period of time like an hour or so) I no longer can.

Log output:
