Hi everyone, We're running an on-prem Kubernetes cluster using MetalLB (Layer 2 mode) and HAProxy for load balancing. The issue we're facing is that all monitoring-related pods (Prometheus, Grafana, Alertmanager, etc.) are healthy and running. We can also access Prometheus from within the cluster and verify alerts through the CLI. However, the monitoring UI URL becomes inaccessible from outside the cluster. What's interesting is that if we either: - Reboot the node, or - Redeploy the MetalLB L2Advertisement the monitoring URL starts working again, but only for about 5 minutes before becoming unreachable. Current observations: - Monitoring pods remain healthy throughout. - MetalLB speaker/controller pods are healthy. - LoadBalancer IP is assigned correctly. - HAProxy is being used in front of the cluster. - No application-level errors observed. - CLI access to Prometheus continues to work even when the URL is down. Has anyone seen similar behavior with MetalLB Layer 2 mode and HAProxy?…
