[SOLVED] ERROR: VM 255192028 qmp command 'backup' failed - got timeout

Hi,

we have added a new 3-Node-Proxox Cluster which has Version 7.1.7 Installed.
This Cluster has Problems to create Backups on our Proxmox Backup Server which is currently 2.0-12.

Our existing Cluster which is still on Version 7.0-11 does not have any issues with backing up VMs.

Is there a known issue I am missing?

Never mind.... MTU on BackupServer was wrong
