[SOLVED] Migrate VM across Clusters with Ceph not possible

If I try to migrate a VM (Online or Offline) from one Cluster to another. It will not work.
Both Clusters use Ceph.

But if i put the OS Disk on local-zfs and then migrate it to the other cluster it works.

Error from Ceph to Ceph:

Are the Proxmox VE nodes on the latest packages? There is currently also work underway on the Proxmox VE side to make the export/import more consistent across the storage plugins. Therefore, if it doesn't work just yet, it should so in the near future.
