Added new subnet: Failed to receive preconfiguration file

Problem:

If I try to boot a new VM using a newly created subnet, I am getting this error:

The file needed for preconfiguration could not be retrieved from … The installation will proceed in non-automated mode.

The network itself is working, if I boot the VM with Knoppix:

This is the subnet-setting:

Expected outcome:

Unattended installation working as it does in another subnet.

Foreman and Proxy versions:

Communication status

URL

https://…:8443

Version

2.4.1

Active features

  • DHCP

  • Dynflow

  • Logs

  • Puppet

  • Puppet CA

  • Registration

  • SSH

  • TFTP

Distribution and version:

Debian 10 buster

I also added a new custom-hiera-config as the different subnets should be used by the same smart proxy:

dhcp::pools:
 45.xx.xxx.48:
   network: 45.xx.xxx.48
   mask: 255.255.255.240
   gateway: 45.xx.xxx.49
   range: 45.xx.xxx.xx 45.xx.xxx.63

and rerun the installer without problems.

But unfortunately now even the ipse-boot itself does no longer work.

Hello,

if you say network is okay, then pastebin production.log from Foreman with that request that is serving the /unattended request for your host. What is the result HTTP status? Any error messages?
