Hi,
I'm in front of a strange behaviour,
I reinstalled proxmox on the same server as before (a debian), I configured the same network and the same containers, except that it is impossible to start my containers.
I got this error :
root@ns3035176:~# systemctl status lxc@100.service
● lxc@100.service - LXC Container: 100

If someone can help me, it would be very grateful,

I restarted my proxmox server based at OVH but he didn't restart, i can't join him by ping, so i can't get the debug log.
Before the crash, i've tried to create some other container with multiple configuration and I found that when the container was connected to the bridge vmbr2 I could not start it.
So, i think my problem is coming from the network configuration file, but it was working on my previous proxmox :
auto lo
iface lo inet loopback

iface eth0 inet manual

iface eth1 inet manual

auto vmbr0
iface vmbr0 inet static

bridge_stp off
bridge_fd 0
