How to bind IPv4 in fleet server

Elastic Stack Elastic Agent
1

Hello, I am trying to set up elastic agent with IPv4 bound. I set up like this:

sudo elastic-agent enroll \
  --fleet-server-es=https://10.0.0.1:9200 \
  --fleet-server-service-token=AAEAAWVsYXN0aWMvZmxlZXQtc2VydmVyL3Rva2VuLTE3MjQyNDYyMTQ1OTY6MDJ0MTRXQWxRQU93aEVuQjlMTHo4Zw \
  --fleet-server-policy=fleet-server-policy \
  --fleet-server-es-ca-trusted-fingerprint=f5bed68b70e82d4df44168279aa67bcf127577a76e3e7b57f53855827e2d2964 \
  --fleet-server-port=8220
  --fleet-server-host=0.0.0.0

But it gave me an error:
--fleet-server-host=0.0.0.0: command not found
I am on ELK system version 8.15.0
What command can I use to bind IPv4 now?
Thanks

tcp6       0      0 :::8220                 :::*                    LISTEN      1527389/fleet-serve

This is netstat result. I want to listen on tcp instead of tcp6.

Hi, you don't have to provide fleet-server-host, it will start fleet-server on your local machine.
