Hi Vishwas, Usually, this issue happens because of: 1. Default service account doesn't have permissions to use the endpoint to get all related IP addresses (of Ignite nodes). 2. A cluster is deployed in not default namespace. For example, in Openshift namespace is a project name.
To resolve that you need to create a service account and grant necessary permissions (we don't need cluster-admin role): *sa.yml* *role.yml* *rolebind.yml* Do not forget to replace <namespace>, add `serviceAccountName` into DeploymentConfig [1] and specify namespace property of TcpDiscoveryKubernetesIpFinder [1].
