bob james resolved as Fixed

The reason I was receiving the error is because my jenkins master was residing behind an ALB which doesn't support TCP listeners as required by JNLP. To work around this, I have created an NLB with a TCP listener and jenkins target group on port 5000. I then proceeded to place the DNS of the NLB in the "Jenkins tunnel" field of the kubernetes-plugin which allowed the agent to establish communication with the master!
