Today, out of the blue I am suddenly unable to log in to my Proxmox Web GUI.
Additional users work (e.g sub-users who can access some machines). Using 'root' will not work whatsoever, it just errors with 'Login failed. Please try again'. There are two machines in the cluster, both...
I renamed one of my nodes today, the Virtual Machines are online and functioning normally however the node is in a 'unknown' state (the grey icon).
This node is in a cluster.
