Elasticsearch search guard SSL error in Google Kubernetes Engine(GKE)

I have few pods elastic search, auth server which communicates with each other. I have updated the image path in those pods lately and since then my auth server unable to connect to elastic search and it is giving the error "SearchGuardSSLNettyTransport:97 - [Victor Strange] SSL Problem General SSLEngine problem" and also I can see from the logs that "Search Guard 2 plugin not available".

I am looking for someone who has experience working on Elasticsearch search guard and Google Kubernetes Engine(GKE).
