I am trying to create k8s cluster with haproxy as external load balancer ( 2 haproxy nodes, 3 control planes , 3 workers) currently am still trying with 2 haproxy and 2 control planes
ERROR : connection between cluster and load balancer is not stable ,, sometimes its UP and then its DOWN again and going in cycles and I didn’t understand why
Logs of the proxy
enter image description here
and when I try the cmd kubectl get nodes I get different errors (when haproxy is down )
<code>kubectl get nodes
Unable to connect to the server: EOF
kubectl get nodes
Error from server: etcdserver: request timed out
kubectl get nodes
Error from server: etcdserver: leader changed
</code>
<code>kubectl get nodes

</code>
kubectl get nodes
