Linux bridge will not activate

[cjkeist]

New user to Proxmox and testing out Proxmox install with a two-node cluster. Running 6.1-3. Everything was working great and then something changed where my first node Linux bridge vmbr1 de-activated. Now any VM assigned to that Linux bridge will not see the network. What happened was I tried to delete a VM that was configured on HA. It gave me an error that I couldn't delete the VM. So I went to HA and removed that VM from the list. I then was able to delete the VM. I think I the VM was originally created on node 1, and then migrated to node2 when I then deleted the VM. When I tried creating a new VM on node1 is when I found that the vmbr1 network was no longer active.
I tried to remove and re-create, reboot the server and still that vmbr1 will not activate. Looking for any help on why I cannot get this to activate. vmbr1 is using eno4. The vmbr1 on node2 is working fine.

Found it. When I tried to bring up the bridge via command line I got this:
ifup vmbr1
error: ignoring interface vmbr1. Only one object with attribute 'bridge-vlan-aware yes' allowed.
error: cannot find interfaces: vmbr1

Back in the web gui I edit and the vmbr1 interface and unchecked the "VLAN Aware" option. Now it's activated!
But will VM's still be able to access the different VLANS on this bridge? I will test and found out.

Have you tried to remove this line

 auto eno4

and keep the vlan aware setting for vmbr1?
