Backup failed unable to connect to VM socket

One of 10 or so kvm's failed backup. A few before and after did a complete backup

I tried qm unlock 105 , and tried backuping up to local instead of nfs and got the same result.

Any suggestions?

I just realized : this node did get pve deb updates a couple of days ago , but can not be rebooted until later this weekend as it is in use. So after that reboot I'll try to backup VM 105.

After rebooting the node, the backup succeeded .
