==================Trying to solve problems========================= cilium hubble disable cilium config set hubble.peerService.clusterDomain "cluster.myk8s" cilium config view | grep clusterDomain hubble.peerService.clusterDomain cluster.myk8s

cilium hubble enable --relay --ui

The problem remains.

==================Solve problems=========================

cilium hubble disable

helm upgrade cilium cilium/cilium --version 1.15.5 \ --namespace kube-system \ --reuse-values \ --set hubble.peerService.clusterDomain="cluster.myk8s" --set hubble.relay.enabled=true \ --set hubble.ui.enabled=true

cilium hubble enable --relay --ui

kubectl get pod -A -o wide kube-system hubble-relay-6446b75c8c-hcg2d 1/1 Running 0 32s

Hubble Relay pod is running successfully.

I don't know what the root cause of the problem is.
