How can I tell packer which IP it should connect to?

Hello.

I’m using the tool for the first time.

I managed to spin up a Debian 10 instance along with it’s preseed file on my Windows 10 Hyper-V hypervisor.

I’m able to SSH manually to my instance, however the packer tool is stuck on "Waiting for SSH to become available…"

Is there something to setup in order for the tool to know which IP it should try to connect to ?

Regards.
