The issue was that the SSH key used by the Dashboard (`config/ssh/id_rsa_dashboard`) was not authorized on the Minecraft server (`192.168.178.8`), causing the "Permission denied" error when the application tried to list backups.

I have fixed this by adding the dashboard's public key to the `authorized_keys` on the remote server using your existing shell access.

The backups are now showing up.

**Important Note:**
I noticed that the backup files and directory (`/home/pepe/minecraft/backups/`) are owned by `root`. The dashboard connects as user `pepe`. This means:
- ✅ **Listing backups:** Works (files are readable).
- ❌ **Creating/Deleting backups:** Will likely **fail** because `pepe` does not have write permissions on the `root`-owned directory.

To fix the creation/deletion, please run this command on your Minecraft server (or via SSH):
```bash
sudo chown -R pepe:pepe /home/pepe/minecraft/backups
```
