Hello I ran into any issue when. When creating a LXC with a static IP it is unable to connect to the internet, but is able to ping google. Then when I switch it to DHCP it is able to connect to the internet. I had used just containers before and the issue didn't occur previously. But once I created a VM for the first time this issue started and the VM does have internet but none of my containers now do.

Proxmox Network Config
auto lo
iface lo inet loopback

iface eno1 inet manual

auto enp2s0
iface enp2s0 inet manual

auto vmbr0
iface vmbr0 inet static
address 10.0.14.80/24
gateway 10.0.14.1
bridge-ports eno1
bridge-stp off
bridge-fd 0

auto vmbr1
iface vmbr1 inet manual
bridge-ports enp2s0
bridge-stp off
bridge-fd 0

source /etc/network/interfaces.d/*

This is what I get when running ping 8.8.8.8 and ip a on the LXC with a static, but unable to apt update
