internet down on boot

[chuchodavids]

Recently installed Proxmox in a Gigabyte Vision G Z490. Every time I reboot the computer the internet interfaces are down. The only way to make it work is by doing ifdown -a and then ifup -a.


this is the /etc/network/interfaces file:
auto lo
iface lo inet loopback
iface enp4s0 inet manual
auto vmbr0
iface vmbr0 inet static
address 192.168.200.28/24
gateway 192.168.200.1
bridge-ports enp4s0
bridge-stp off
bridge-fd 0

this is the IP a output after doing ifdown and ifup:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

Hello,

Please see if there any error from boot to see that you can use journalctl -b or dmesg

nothing. It seems like the Ethernet card is not compatible. I just clean installed it using my 10gbe card and it worked no problem

Hi,

Please post version of your Proxmox pveversion -v
