New install - Set up wizard failing at uploading configuration

[Alphabetic]

Hi all

I've spun up a new VM and installed the ISO.

I'm able to access the set up wizard from the internet and ping out to the internet from the VM.

I've tried the URL and uploading the config file but i'm getting the following:

Im seeing this - could this be the cause? It's a VM on Hetzner - I even made a firewall rule to allow all but got the same error.

Ok just a little bit further down it says:

2025/10/10 15:44:12.871|0019|Info| [PbxWebConfigTool.Controllers.HomeController] Invalid answer error
PostInstall.InvalidAnswerException: Error in XML file. RequestCode = 'PublicIP': Invalid option selected
   at PostInstall.MenuTree.GetInstallationSettings(MenuNode rootMenuNode, SetupSettings setupSettings)

it seems to be failing detecting the WAN.

I downloaded the XML and modified it:

     <code>PublicIP</code>
      <answer>manual</answer>
    </option>
    <option>
        <code>ManualPublicIP</code>
        <answer>X.X.X.X</answer>
</option>

and now it has progressed.

Im having more issues with the firewall checker passing so i've put it down to a Hetzner problem and i've scrapped the machine.
