I recently installed Elastic Security following the belowlinked YouTube video:

[![](https://us1.discourse-cdn.com/elastic/original/3X/6/0/6012e09fe157cc8069ec443c85df9e15896b6c37.jpeg "Setting Up Elastic 8 with Kibana, Fleet, Endpoint Security, and Windows Log Collection") ](https://www.youtube.com/watch?v=Ts-ofIVRMo4)

Under Management \> Fleet it is showing "Fleet Server is not Healthy. A healthy Fleet server is required before you can enroll agents with Fleet.". And, under Agents, it is showing only 1 agent, the Fleet Server which has an unhealthy state under "Endpoint Security" saying:

```auto
The endpoint's connection to Elasticsearch is either down or misconfigured. Make sure it is configured correctly

```

Do you have any recommendations on what I can do to troubleshoot?

Hi @Timothy_Dilbert I recommend taking a look at this project that uses Elastic Security in a container: [The Elastic Container Project for Security Research | Elastic](https://www.elastic.co/pt/security-labs/the-elastic-container-project)

It even comes with the fleet server configured.
