I'm was scratching my head at this. My other LXCs are from the same template. I just tried to spin up a third container and it failed to start. Closest error was this thread, but this thread was my problem. I had pfSense not proving a DHCP address on that VLAN to unknown clients. Enabled DHCP to give an IP and the container came right up. Sharing for posterity if it ever helps someone in their search results.

Code: 
root@Proxmox:~# pct config 103
arch: amd64
cores: 1
hostname: backup
memory: 1024
net0: name=eth0,bridge=vmbr0,firewall=1,hwaddr=9A:16:4E:E4:5E:61,ip=dhcp,tag=53,type=veth
ostype: debian
rootfs: local-lvm:vm-103-disk-0,size=8G
swap: 512
unprivileged: 1

Code:

Yes, it is resolved. Did I not mark it correctly that it is resolved? The post is solely for others to find it in search as I spent over an hour trying to figure it out.
