Authentication failed when migrating

I have four Proxmox nodes and I have some VMs setup and running on the first node. I migrate a VM from node one to either node two, three or four. I lose console connection even though it is an online migration. When I try to open the console back up, it gives these messages in this order:

Status: X509
Status: Plain Authentication
Error: Failed Authentication

If I move the VM back to the first node, the console will start working again.
 
Any ideas? I am still getting this message. I can't access any of the VMs that aren't running on my first node.
 
I have tried that. I have even tried stopping the VM after migration and starting it back up.
If I move the VM back to Node 1 then the console window will come up.

Maybe something wrong with the certificates. Try:

# pvecm -f updatecerts

The restart that server.
 
I tried that. I am still having the same issue. I do have the Proxmox nodes setup in a HA cluster.
 
I tried an offline migration. Proxmox says:
Executing HA migrate for VM 100 to node KNTCLCN003
Trying to migrate pvevm:100 to KNTCLCN003...Temporary failure; try again
TASK ERROR: command 'clusvcadm -M pvevm:100 -m KNTCLCN003' failed: exit code 250

When I execute the command "clusvcadm -M pvecm:100 -m KNTCLCN003" directly into the console, I get:

I noticed this in the Proxmox interface under syslog for KNTCLCN003:

That got me to thinking. I placed all my nodes in a cluster before accessing the Proxmox interface. I accessed Proxmox Web Interface from the IP address of the first node in the cluster. I never went to the other nodes. It never did ask me to log into nodes KNTCLCN003 and KNTCLCN004 when I logged into the first node. Maybe because nodes 3 and 4 never asked for a username/password, then I am not authenticated on them as far as proxmox is concerned?

So I go to the IP address of each node and log in. Still no luck. Then I tried migrating a VM from KNTCLCN001 over to KNTCLCN003. I then went to the IP address of KNTCLCN003 and was able to pull up the console for the VM. So apparently, I can only access the VM from the node that it is running on. Odd, but at least there is a solution.

Seems there is something wrong with the time on that host? Please make sure that all nodes have correct time.
