[BETA] [HPE] VM Backups fail on new Nodes added to Cluster

[bent502]

My 3 Node VME cluster backups worked flawlessly. After adding two new VME Hosts to the existing Cluster and moving VMs to those Nodes, those VMs' failed to backup. I tried rescanning the Cluster in Veeam, rebooting Veeam, setting up a new backup job for VMs on that specific Host with a worker on that host, all to no avail.
I moved the VMs back to one of the original hosts, and the backup was successful.
How do you force Veeam to see the new nodes like it does the originals?

BUM365 : Failed to perform backup: Failed to connect to the host [localhost] using the TCP protocol (port [51086]). nbd_connect_tcp: connect: localhost:51086: could not connect to remote host: Connection refused. -1 (0:00:18)

For this VM - it is on the same network as the VME Manager, Veeam B&R, VME Hosts, and Veeam-Workers (no firewalls in between)

Here is a small snip of what may be the issue from that VMs backup log,

2025-12-23 23:02:06.6920 00005 [1494] INFO | [Domain]: Successfully started the backup job

The IP above is my new VME Host, where the VM being backed up is running.

Have Merry Christmas! -
