I tried setting up TLS with reference to [Encrypt traffic in a self-managed cluster | Fleet User Guide [7.13] | Elastic](https://www.elastic.co/guide/en/fleet/current/secure-connections.html).

However, I faced `Error: fail to enroll: fail to execute request to fleet-server: x509: certificate signed by unknown authority` without the insecure flag.

Exact flags was used on a centos container and was able to enroll successfully provided with the exact certificates.

Following is my docker-compose config to run the fleet server in my infrastructure.

```auto
fleet_server01:
    image: docker.elastic.co/beats/elastic-agent:${VERSION}
    container_name: fleet
    ports:
      - 8220:8220
    networks:
      - elastic
    hostname: docker-fleet-server
    volumes:
      - ./certs:$CERTS_DIR
    environment:
      FLEET_SERVER_ENABLE: 1
      FLEET_URL: $FLEET_URL #Host IP,Port 8220
      FLEET_CA: $CERTS_DIR/ca/ca.crt
      FLEET_SERVER_CERT: $CERTS_DIR/fleet_server01/fleet_server01.crt
      FLEET_SERVER_CERT_KEY: $CERTS_DIR/fleet_server01/fleet_server01.key
      FLEET_SERVER_ELASTICSEARCH_HOST: $ES_URL #Host IP, Port 9200
      FLEET_SERVER_SERVICE_TOKEN: $SERVICE_TOKEN
      FLEET_SERVER_ELASTICSEARCH_CA: $CERTS_DIR/ca/ca.crt
      FLEET_SERVER_POLICY_ID: $FLEET_POLICY_ID
      #FLEET_INSECURE: "true"

```

You need to make sure that the `FLEET_URL` matches the name defined in the `FLEET_SERVER_CERT`. If it does not match exactly it will fail with the given error.
