I created a staging node and production node, I downloaded the agent.jar and slave-agent.jnlp for both nodes, and copy them to the servers.

I tried this command - java -jar agent.jar -jnlpUrl http://54.164.155.216:80 80/computer/production/jenkins-agent.jnlp -secret 0f69af1947110e62d0696f49aa07e0 7d30387478c6b1d0ae204b8aab6943baf6 -workDir "/home/ubuntu/jenkins"

I go the error below. I could establish a connection to the "built-in node", which I believe is the master node..Right?

Or do I need to create a master node and delete the built-in node that was there when I logged into the Jenkins?
