Proxmox 8.1.10. Сервер расположен у hetzner. Две ночи подряд сервер теряет доступ в Интернет. Перезагрузка не помогает. Помогает только *service networkmanager restart* - через KVM. Где копать решение проблемы?

# If you want to manage parts of the network configuration manually,

# PVE will preserve these directives, but will NOT read its network

# the PVE managed interfaces into external files!
