The assignment of private networks happens in the hetzner cloud after starting the server and therefore often after querying the network information when assigning VIPs. If an alias IP is to be set but no private network is yet available, an error message is now thrown, until the private network is assigned. Previously, no error message was thrown and the network ID was set to 0, which means that the VIP is regarded as a public floating IP in the further code and not as a private alias IP.
