Ct config

You have two network, 144.76.197.160/27 and 144.76.161.128/29
Gateway on Proxmox host - 144.76.197.161
For VMs available only second network.
In you config vmbr0 has IP 144.76.161.129
(for /29 mask: 144.76.161.128 - network, 144.76.161.135 - broadcast)
For VMs available IP: 144.76.161.130, 144.76.161.131, 144.76.161.132, 144.76.161.133, 144.76.161.134 and gateway must be 144.76.161.129

If you get from Hetzner not network, simply 8 IPs, look sample here: https://dominicpratt.de/hetzner-proxmox-network-configuration/
