Nuc error QEMU exited with code 1

Hi I am pretty new to Nuc’s - I have had my setup running fine for months but today I got one of many power cuts and got the QEMU exited with code 1 error. I just cant get it to start. Can you please advise how I can get back up and running?

Did you ever resolve this, and, if so, how? I am getting the same error message from Proxmox.

To be honest I cant recall how I resolved it. I’m pretty sure it was fairly straightforward and associated to losing network information. May be better to try the Proxmox forum.
