Node is Not connecting with Kubernetes.DNSSRV

Hi,

I'm using Elixir.Cluster.Strategy.Kubernetes.DNSSRV for libcluster in AWS EKS where I enabled Istio also.

Here is my configuration:

` strategy: Elixir.Cluster.Strategy.Kubernetes.DNSSRV,
config: [
service: "settings-v3-service",
namespace: "kandula-dev",
application_name: "settings",
polling_interval: 10_000
],
connect: {:net_kernel, :connect_node, []},
disconnect: {:erlang, :disconnect_node, []},
list_nodes: {:erlang, :nodes, [:connected]}
]
`
I'm using stateful sets.
If I do hostname -f cmd it gives like this: "settings-0.settings-v3-service.kandula-dev.svc.cluster.local"
My node name structure is like this: "settings@settings-0.settings-v3-service.kandula-dev.svc.cluster.local"

If I use Node.connect I can able to connect.

But with libcluster it is not connecting. it throws the below error.

the log is throwing this error:

`
2020-11-26T10:00:02.191644371Z 10:00:02.191 [warn] [libcluster:kandula_settings] unable to connect to :"settings@settings-v3-service.kandula-dev.svc.cluster.local"

`

If I do `dig SRV settings-v3-service.kandula-dev.svc.cluster.local` it is not returning my stateful set list.

dig srv command result:

`
root@settings-0:/app# dig SRV settings-v3-service.kandula-dev.svc.cluster.local
