Cannot run agent Pod for Jenkins 2.346.2 on Kubernetes

[Jim Leary]

I have an older version of Jenkins that is running agent pods just fine - no changes to the Kubernetes Plugin config after install via Helm Chart.

Now, with the same cluster, I installed Jenkins 2.346.2 using Helm Chart v4.1.13 and I am getting the error java.net.SocketTimeoutException below.  I have done everything from increasing the timeouts on the Kubernetes Plugin to spinning up a new cluster (AWS EKS v1.22) just to test there as well.  There is nothing special about these clusters - very generic.  I have also tried using the clusterIP of the Jenkins service, but still nothing.

Thanks.
