Hallo,
I've updated two of my Proxmox Backup Servers (Boot:BIOS-Mode) from 3.4 to 4.0.12. They are running in a VM
I am Useing PVE 8.4.9.
When I start the backup of my LXC (from my PVE Host) to my PBS it gets stuck in the Upload and Fails.
The Same PVE Host has no Problem backing up the Same CT to a different PBS host with the Version 3.4.4 (UEFI-Boot)
Another Conatiner (CheckMK) doesn't work with the new PBS 4.0.12. (cannot test to the old one at the moment.)
I get this error:
Both Containers have no Problem Backing up to the local drive in Snapshot mode.
Edit: I tried adding a new disk to one of the upgraded Backup Servers but there is no difference. I am Using root as my User
