So I've been struggling to get this working. I installed Kibana with Elasticsearch via auto configuration on Linux. Kibana connects to Elasticsearch no problem via https. However, I can't get apm-server to connect to elasticsearch via https. I have the following in apm-server.yml ... output.elasticsearch:hosts: ["https://:9200"] I also have username and password set. My services show up in the apm-server logs. However, they don't show up in Kibana under APM/Services. apm-server shows an error saying ... **"precondition failed: x509: certificate signed by unknown authority"** How do I fix this? Based on reading Elastic docs, I need to point apm-server.yml to the Elastic certificate and cert authority. I don't know the exact steps for that. Can someone help? ---

By the way, this is a dev server installation. ---
