This one has me mystified. I'm trying to set up a simple dev environment with elastic-agent shipping logs to a single-node Docker instance of Elasticsearch. All on my local machine.

But when I try to start up elastic-agent as the fleet server, it somehow decides to change the fleet server url from `https://127.0.0.1:8220` to `https://laptopname:8220`. Then, to rub it in, it grabs the dns ip address from our internal dns server and tries to connect to that ip address.

(Note, that dns entry is only accurate when I'm in the office, so agent times out when trying to connect to it. Plus, I don't have 8220 open on my firewall.)

It does the same thing if I use `localhost` or set a `blah.local` value in `/etc/hosts`.

```bash
# ./elastic-agent install \
> --fleet-server-es-ca=/var/lib/docker/volumes/es_config/_data/certs/elasticsearch-ca.pem \
> --fleet-server-es=https://127.0.0.1:4704 \
> --fleet-server-service-token=token \
> --fleet-server-policy=fleet-server-policy
Elastic Agent will be installed at /opt/Elastic/Agent and will run as a service. Do you want to continue? [Y/n]:y

Anyone have any ideas what is going on? This is not expected behavior. When presented with localhost, I expect any tool to just stop and use it. So it's really really weird that elastic-agent is grabbing my hostname and resolving it.

This is elastic-agent version 8.3.3. On PopOS 20.04.

Thanks in advance!
