Does it work if you do not pass the `--insecure` flag?

So I got the Fleet server agent running and I see it in Kibana using this install
```auto
### Fleet Server Installation
curl -L -O https://artifacts.elastic.co/downloads/beats/elastic-agent/elastic-agent-8.3.2-linux-x86_64.tar.gz
tar xzvf elastic-agent-8.3.2-linux-x86_64.tar.gz
cd elastic-agent-8.3.2-linux-x86_64
sudo ./elastic-agent install --url=https://:8220 \
--fleet-server-es=https://:9200 \
--fleet-server-service-token=AAEAAWVsYXN0aWMvZmxlZXQtc2VydmVyL3Rva2VuLTE2NTgzMzY5MDI4NTk6YXRPbHV6RHhRZTJIY09EZ213RTEtUQ \
--fleet-server-policy=fleet-server-policy \
--certificate-authorities=/tmp/certs/ca.crt \
--fleet-server-es-ca=/tmp/certs/http_ca.crt \
--fleet-server-cert=/tmp/certs/fleet-server.crt \
--fleet-server-cert-key=/tmp/certs/fleet-server.key
```
and it's running
I also installed a Fleet managed elastic agent using:
```auto
### Elastic Agent Installation
curl -L -O https://artifacts.elastic.co/downloads/beats/elastic-agent/elastic-agent-8.3.2-linux-x86_64.tar.gz
tar xzvf elastic-agent-8.3.2-linux-x86_64.tar.gz
cd elastic-agent-8.3.2-linux-x86_64
sudo ./elastic-agent install --url=https://:8220 --enrollment-token=LTE0YkhZSUJ2cHZnVk1wM1JrM2E6TjJjeHRURi1SSnVNckluaGstbW95QQ== --insecure
```
and it is running and I see it in Fleet in Kibana (both Fleet server agent and elastic agent).
However both the Fleet agent and the elastic agent are not sending their internal logs to Elasticsearch, the error I am seeing on each agent from /opt/Elastic/Agent/data/elastic-agent-16c55b/logs/ is:
```auto
{"log.level":"error","@timestamp":"2022-07-21T14:02:38.372Z","log.logger":"esclientleg","log.origin":{"file.name":"transport/logging.go","file.line":38},"message":"Error dialing x509: certificate signed by unknown authority","service.name":"filebeat","network":"tcp","address":":9200","ecs.version":"1.6.0"}
```
the cert I used for the Fleet agent to communicate with elasticsearch is http\_ca.crt and I grabbed it from the elasticsearch server from /etc/elasticsearch/certs/http\_ca and when I curl from the Fleet server host or from the host running the elastic-agent to https://:9200 it works
```auto
curl --cacert /tmp/certs/http_ca.crt --user elastic https://:9200
```
returning:
```auto
{
"name" : "node-1",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "PCVh7o6xQy2qJkVJMPjM5w",
"version" : {
"number" : "8.3.2",
"build_type" : "rpm",
"build_hash" : "8b0b1f23fbebecc3c88e4464319dea8989f374fd",
"build_date" : "2022-07-06T15:15:15.901688194Z",
"build_snapshot" : false,
"lucene_version" : "9.2.0",
"minimum_wire_compatibility_version" : "7.17.0",
"minimum_index_compatibility_version" : "7.0.0"
},
"tagline" : "You Know, for Search"
```
So I am not sure what I am missing here.

Ok - finally got this working. The solution was to add the line below under Fleet \> settings \> outputs in the "Advanced YAML configuration" field
```auto
ssl.certificate_authorities: ["/path-to-es-cert/http_ca.crt"]
```
