Installing fleet server on Ubuntu 20.04 fails with:
```auto
Error: fail to enroll: fail to execute request to fleet-server: status code: 400, fleet-server returned an error: BadRequest
```
The command i'm issuing is:
```auto
./elastic-agent install --url=https://ip.of.this.server.for.fleet:8220 \
--fleet-server-es=http://dns.of.es.server:9200 \
--fleet-server-service-token=THIS.IS.THE.TOKEN \
--fleet-server-policy=44eb5270-2544-11ed-8ca6-a96eff51e786 \
--fleet-server-es-ca=/opt/fleet/certs/elastic-stack-ca.crt \
--fleet-server-cert=/opt/fleet/certs/fleetserver.crt \
--fleet-server-cert-key=/opt/fleet/certs/fleetserver.key \
--certificate-authorities=/opt/fleet/certs/elastic-stack-ca.crt
```
I am using the same CA for the fleet certs and elasticsearch certs.
There doesn't seem to be any additional info, the full output from the command is:
```auto
Elastic Agent will be installed at /opt/Elastic/Agent and will run as a service. Do you want to continue? [Y/n]:y

Are their any debug switches I can specify in order to get more information.
Thanks

My testing doc has tracks where basically the same command worked, then when I went to add another client, it failed. I just used --insecure and it worked, it was a test system only.
Watching for other solutions 🙂

Hi,
I had the same problem when I tried to install the fleet server in production mode without passing the --insecure option.
I think that the problem here is that --fleet-server-es-ca and --certificate-authorities can't be the same.
Follow this link to generate your certificates and to install your Fleet Server : [Encrypt traffic in clusters with a self-managed Fleet Server | Fleet and Elastic Agent Guide [7.17] | Elastic](https://www.elastic.co/guide/en/fleet/7.17/secure-connections.html)
I'm working with 8.3 and I followed [Configure SSL/TLS for self-managed Fleet Servers | Fleet and Elastic Agent Guide [8.3] | Elastic](https://www.elastic.co/guide/en/fleet/8.3/secure-connections.html) which successfully worked so I think it will work for you as well.
Also, in the Fleet settings in Kibana UI, don't forget to add in Output \> Advanced YAML configuration field : ssl.certificate\_authorities: ["path/to/fleet-server-es-ca"] so here with your certificates it would be ssl.certificate\_authorities: ["/opt/fleet/certs/elastic-stack-ca.crt"].
Hope it will help you !
