[SOLVED] Proxmox 7.2 without network connection

[breunion]

I recently installed PROXMOX VE 7.4 by performing the network settings in the installation utility itself, since then I have had difficulties getting my proxmox to ping on the local network or any other type of network connection.:

# cat /etc/network/interfaces

auto lo
iface lo inet loopback

iface enp7s0 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.0.250/24
gateway 192.168.0.1
bridge-ports enp7s0
bridge-stp off
bridge-fd 0
iface enp4s0f0 inet manual

iface enp4s0f1 inet manual



#brctl show
bridge name bridge id STP enabled interfaces
vmbr0 8000.00e00a738627 no enp7s0

The latest version is Proxmox VE 8.1 and definitely recommended for new installations.
Is there an actual reason why you used 7.4?

Anyway, what is the exact error when trying to ping any other host on the network? What have you tried so far in regards to troubleshooting?
Can you also please post the output of ip a and ping 192.168.0.1?

What's the general network configuration? Have you checked whether a) the subnet mask and gateway are correct and b) if there are maybe some IP address collision?

Thanks for the answer.
I just updated to the newest version, but the error still persists.

error mensage:
#ping 192.168.0.1

Today I installed the same Proxmox on another computer and it worked.
The problem is possibly with the computer's network card.
Right?

The problem was with my network card.
Solved as soon as the network card was replaced.
