Kimchi/Wok fails after a reboot

I had kimchi/wok running smoothly on a CentOS 7 base. Until I rebooted. Now I am getting a nginx 502 Bad Gateway error. The wok-error.log does not show anything obvious other than a unknown device type drm Qemu-kvm is running because I can connect to the kvm from a remote machine.

Push server created on address /run/user/0/woknotifications
