Trouble mounting cifs share

[Franz Geffke]

I'm having trouble mounting cifs; Initially I thought it's a network issue of some sort, but it happens on a number of systems and I assume the Hetzner Storagebox is OK (as in, configured correctly):

- 2x 6.6.2-gnu Guix: Failed
- 1x 6.1.0-13 Debian: Failed
- 1x 5.10.0-21 Debian: Success

Here's what I'm trying (always as root):

```
mount.cifs -o user=abc,pass=abc //abc.your-storagebox.de/backup /mnt/storage-box
```

SUCCESS:

```

```

FAILURE:


```

mount error(2): No such file or directory

```

dmesg first run:

```

dmesg second run:

```

[84327.549388] CIFS: VFS: cifs_mount failed w/return code = -2
```

third one, directly after 2nd:

```
mount.cifs -o user=abc,pass=abc //abc.your-storagebox.de/backup /mnt/storage-box
mount error(126): Required key not available

```

dmesg third run:

```

```

Am I missing something? Thank you.
