does anybody know how to implement Nexus HA in a Kubernetes Cluster running in EKS?

I've installed Hazelcast with Helm and deployed Nexus with a Helm Chart too.

3 Pods are running but, when I'm looking into the container logs, I can't see the cluster formed by the 3 pods.

When I'm connecting to the DNS Nexus in a browser I got the error message: Application will be reloaded as the server has been restarted.
