[Bug]: Cannot assign a private server to a subnet without other IP/Interface assigned #1265
Description
What happened?
Hi Team,
I've encountered an issue when trying to use the new subnet assignment feature from v1.56.0 (#1217).
When creating a VM without a network block or public IP enabled (expecting hcloud_server_network to handle the subnet assignment), the hcloud_server resource fails. The creation fails as the instance cannot start because it has no interface assigned at creation time.
The VM should be created and then have its network/subnet assigned via hcloud_server_network.
Has anyone else encountered this?
Regards!
Log:
Error: hcloudutil/WaitForAction: no public or private network interfaces found, cannot start server (invalid_input, 593478587344330)

Please provide a minimal working example
Problematic code
resource "hcloud_server" "test" {
depends_on = [hcloud_network_subnet.subnet]
name = "debian-test-fsn1-staging"
server_type = "cax11"
datacenter = "fsn1-dc14"
image = "debian-13"
keep_disk = true
backups = false
labels = merge(var.labels, {})
shutdown_before_deletion = true
ssh_keys = [hcloud_ssh_key.env.id]
public_net {
ipv4_enabled = false
ipv6_enabled = false
}

alias_ips = []
}Enabling public IP fixes the problem.
