Hi, I am on elasticsearch-7.13, and for rules section I am getting message " You must enable Transport Layer Security between Elasticsearch and kibana". I've enabled SSL with let'sencrypt certificate on a nginx reverse proxy. I've set `elasticsearch.hosts: ["https://elasticsearch.xyz.com"]`. How do I signal elastic search and kibana that tls is enabled? ---

You cannot. Kibana Alerting relies on functionality within Elasticsearch that is only enabled when you run on HTTPS inside Elasticsearch. There is currently not way to bypass that requirement with a proxy. ---
