Hello, We're evaluating ElasticSearch and for this we're trying to deploy a cluster against our production data. For now, the goal is to index and see the performance on some obvious queries. We have deployed 2 nodes and "secured" them using an NGINX proxy which "hides" them behind HTTPS with Basic Auth. Each node work well individually, but they fail to communicate with each other. I understand that multicast will not work since we use nginx, so we configured the nodes using this: discovery.zen.minimum\_master\_nodes: 2 discovery.zen.ping.multicast.enabled: false discovery.zen.ping.unicast.hosts: , How can we specify which ports to use (8080), the fact that it needs to use SSL and credentials for HTTP basic Auth? Is that even doable? If not how can we get both nodes to communicate securely given that we Linode servers (XEN instances in a network that we do not control).

Please disregard, I read more of these docs > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI. See into your data and find answers that matter with enterprise solutions designed to help you build, observe, and protect. Try Elasticsearch free today. and found that changing the HTTP interface does not affect at all the inter-node communciation!
