HAProxy stats not updating on adding new worker nodes

[jessond1982]

I followed same steps to configure OCP4-Metal-install and I successfully configured the cluster with 3 control plane nodes and two worker nodes.
I added additional node to the cluster successfully but the status in not updating in HA-proxy. any changes do I need to perform in HA-Proxy. any support is much appreciated.

[root@ocp-svc log]# oc get nodes
