Can't connect to node

Elastic Stack Elasticsearch

I have a cluster with 5 ES nodes. I am getting the following errors in these node. I am not sure what is causing this and hoping that some one can help. Thanks in advance.

As mentioned in this thread - Timeout/Connection error - you have replaced the default discovery with ZK, you will need to ask the developers of that plugin for assistance.

Please also don't create multiple threads on the same problem :slight_smile:
