Hi, We were running the script and got this error. Any idea of how to fix this? Thanks! ![Screen Shot 2022-01-04 at 12.17.09 PM](https://canada1.discourse-cdn.com/flex030/uploads/replicated/original/1X/1fa6aa7a82080105206de67e87f61085ac08df38.png) ---

Would you be able capture the output ? The Screenshot image is not getting loaded. This page talks about Certificate renewal - [https://kurl.sh/docs/install-with-kurl/setup-tls-certs#manual-renewal](https://kurl.sh/docs/install-with-kurl/setup-tls-certs#manual-renewal) jalaja ---

Thanks. It is error execution phase certs/etcd-server: failed to write or validate certificate “etcd-server”? failure loading etcd/server certificate: failed to load certificate: the certificate has expired ---

Wondering if we rerun a latest kURL script, would that resolve this issue? This is a on-prem deployment therefore we cannot verify it at our side first. ---

Would you be able to provide any extra info about the error message? Sometimes the surrounding lines can help a lot, as can what version of k8s was running. Generally though, following the steps in the manual cert renewal document (`kubeadm alpha certs renew all`, `mv /etc/kubernetes/manifests/kube-apiserver.yaml /tmp/ && sleep 1 && mv /tmp/kube-apiserver.yaml /etc/kubernetes/manifests/`, `mv /etc/kubernetes/manifests/kube-controller-manager.yaml /tmp/ && sleep 1 && mv /tmp/kube-controller-manager.yaml /etc/kubernetes/manifests/`, `mv /etc/kubernetes/manifests/kube-scheduler.yaml /tmp/ && sleep 1 && mv /tmp/kube-scheduler.yaml /etc/kubernetes/manifests/`) will do the trick for expired certificates. ---
