Hi All,

I tried deploying opendistro helm chart in the IPv6 k8s cluster and I am getting the below responses in pod logs

checked the cluster status inside the master pod and below is the response I got,

Attaching the opendistro-es helm which I tried in my IPv6 environment and the same was working in IPv4 k8s cluster.

Does opendistro elasticsearch helm chart not supported in IPv6 k8s cluster?

Please share your thoughts.

I'm having the same issue. 1.13.1 works fine but 1.13.2 and 1.13.3 crash with this error
