Today I encountered the same problem. Proxmox 8.2.4, PBS 3.2-7. When restoring a file via the web interface, an error occurs when mounting "drive-scsiXX.img.fidx/part/1": all mounts failed or there is no supported file system (400). At the same time, on PBS we make a map proxmox-backup-client vm/115/2024-10-18T17:00:02Z disk-sсsi0.img --repository localhost:data0
mount -t ntfs -o ro /dev/loop1p2 /mnt/test3
and there is access to the files

and there is access to the files

We are using same versions, and having same problem but in this case only on a single disk of a vm, disk-2 (disk0 and 1 have no problem).

The only thing we see is that the disk with the problem (disk-2) is resized/expanded, and it looks like after that it isn't working any more for the specific disk
