No network after restart Containers

[Kaboom]

Good afternoon,

Running xx nodes with Ceph and Proxmox 6.2.
Kernel 5.3.18-3
Kernelcare
Centos7 containers

When I shutdown a container in Proxmox and start it again it will have no network connection. When I do a reboot in ssh with for example 'init 6' it works again.

I have this problem after upgrading to the latest Proxmox 6.2 version. I have this problem only on all my containers, with VM's no problem at all.

Anyone got an idea what this could be?

Thanks!

After rebooting alle nodes it worked again.
