i have one k8s cluster and has added into gitlab，also i have installed prometheus in k8s and works ok；now i want to integration prometheus，so i enter “admin->kubernetes->Intergration” and check “Enable Prometheus integration”,then “save changes”，when i goto “Health” tag，it show " Connection failed We couldn’t reach the Prometheus server. Either the server no longer exists or the configuration details need updating"。my gitlab version is 14.0.0，prometheus is deploymented in “gitlab-managed-apps” namespace and service name is “prometheus-prometheus-server”。
how can i do?
