Hello @safetylab1976 , I will need a bit more info here. I can run our operator on GKE or EKS 1.21 with no issues. Could you please share more details about your k8s cluster and deployment for the operator and the DB cluster (cr.yaml)? ---

Hello! I’m having the same issue. I followed the instructions indicated here: [Install Percona XtraDB Cluster using Helm](https://www.percona.com/doc/kubernetes-operator-for-pxc/helm.html) to install the operator in Azure AKS 1.22.6 and have the same problem described above. The first node start correctly, but the second one never goes up due to a readiness probe error:: Readiness probe failed: ERROR 2003 (HY000): Can’t connect to MySQL server on ‘10.2.1.117:33062’ Can you help me please? @Sergey_Pronin ---

I was able to reproduce it on AKS. The installation with `kubectl` through regular YAMLs work fine. I created the following JIRA ticket to track this: [[K8SPXC-996] Helm chart installation fails because of TLS cert issue - Percona JIRA](https://jira.percona.com/browse/K8SPXC-996) ---

Hey folks, we have a fix in this PR: [K8SPXC-996 - Fix TLS cert generation by tplavcic · Pull Request #129 · percona/percona-helm-charts · GitHub](https://github.com/percona/percona-helm-charts/pull/129) I checked and it worked for me. If you have a chance - please give it a try and let me know if it works for you. ```auto git clone -b K8SPXC-996 https://github.com/percona/percona-helm-charts cd percona-helm-charts/charts helm install --values pxc-operator/values.yaml --namespace=helm-test pxc-op ./pxc-operator helm install --values pxc-db/values.yaml --namespace=helm-test pxc-db ./pxc-db ``` ---
