Versions (relevant - OpenSearch/Dashboard/Server OS/Browser): 3.2.0
Describe the issue: I have installed successfully bitnami/opensearch on IPV6 cluster and working fine, All pods up and running.
run the same helm chart on IPV4 Cluster (Rocky Linux release 8.10) but always startup failed.
increased the resources and startup, readiness and liveness till 900( 15 mins). Still same issues. PV PVC also bounded in local storage class.
I tried with same opensearch-project helm chart same issues we are facing in IPV4 Cluster.
