can't open nomad ui after vagrant up

Question

I'm trying to setup nomad using vagrant it works and I've being able to connect to vm using ssh and start nomad using :

nomad agent -dev

==> Nomad agent configuration:

       Advertise Addrs: HTTP: 127.0.0.1:4646; RPC: 127.0.0.1:4647; Serf: 127.0.0.1:4648
            Bind Addrs: HTTP: [127.0.0.1:4646]; RPC: 127.0.0.1:4647; Serf: 127.0.0.1:4648
                Client: true
             Log Level: DEBUG
                Region: global (DC: dc1)
                Server: true
               Version: 1.3.1

==> Nomad agent started! Log data will stream in below:

    2025-02-08T00:14:51.959Z [DEBUG] agent.plugin_loader.docker: using client connection initialized from environment: plugin_dir=""
    2025-02-08T00:14:51.959Z [DEBUG] agent.plugin_loader.docker: using client connection initialized from environment: plugin_dir=""
    2025-02-08T00:14:51.960Z [INFO]  agent: detected plugin: name=java type=driver plugin_version=0.1.0
    2025-02-08T00:14:51.960Z [INFO]  agent: detected plugin: name=docker type=driver plugin_version=0.1.0

but when I hit localhost:4646 it doesn't work (no signal)

 $ curl localhost:4646
 curl: (56) Recv failure: Connection reset by peer

I've checked forward ports and they are correct. this is my vagrant config file :

SCRIPT

Vagrant.configure(2) do |config|
  config.vm.box = "bento/ubuntu-22.04" # 22.04 LTS, Jammy
  config.vm.hostname = "nomad"
  config.vm.provision "shell", inline: $script, privileged: false

  # Expose the nomad api and ui to the host
  config.vm.network "forwarded_port", guest: 4646, host: 4646, auto_correct: true, host_ip: "0.0.0.0",protocol: "tcp"

  config.vm.provider "libvirt" do |libvirt|

  config.vm.provider "parallels" do |p, o|
    p.memory = "1024"

        vb.memory = "1024"

  ["vmware_fusion", "vmware_workstation"].each do |p|
    config.vm.provider p do |v|
      v.vmx["memsize"] = "1024"
    end
  end
end

I'm expecting the ui to be available in my browser

I've tried binding to another port but it's not working too.

EDIT : when I execute systemctl status inside vm :

vagrant@nomad:~$ sudo systemctl status

but when I check only nomad :

vagrant@nomad:~$ sudo systemctl status nomad
Unit nomad.service could not be found.

Solution to this problem in my case : start nomad with --bind 0.0.0.0 flag :

nomad agent -dev --bind 0.0.0.0
