All has been fine since installing Proxmox 8.1. Running a simple config with the following:
-----------------------------------------------------------
Proxmox server: 192.168.43.3/24

Home Assistant VM: 192.168.43.4
Plex LXC: 192.168.43.115
Windows VM: 192.168.43.116
------------------------------------------------------------
cat /etc/network/interfaces
auto lo
iface lo inet loopback

iface eno1 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.43.3/24
gateway 192.168.37.1
bridge-ports eno1
bridge-stp off
bridge-fd 0

iface enp2s0 inet manual

iface wlp3s0 inet manual

source /etc/network/interfaces.d/*
---------------------------------------------------------------
No config changes have been made recently. Today I noticed I could not reach the Proxmox web interface, plex, or the windows VM. I could however reach the Home Assistant VM. So all hosted nodes except for HA are unreachable.

I logged into Proxmox CLI and tried pinging out to the LAN and internet that was successful. I was not able to ping any of the devices it is hosting, except for HA.

Tried rebooting Proxmox but that didn't help. I tried disabling ProxMox firewall and that didn't help either.

Any ideas?
