===== mount error(115): Operation now in progress =====
Full error:
  mount error(115): Operation now in progress
  Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

This could happen if it tries to mount via dns name and it resolves to IPv6 e.g. example from fstab:

  #//u111111.your-storagebox.de/backup /mnt/backup-storage cifs iocharset=utf8,rw,credentials=login.txt,file_mode=0660,dir_mode=0660 0 0

Try pinging the **u111111.your-storagebox.de** to get the ipv4 address (''ping -4 u111...'') and enter that in ///etc/fstab/// (example if ping resolves to 11.22.33.44):

  //11.22.33.44/backup /mnt/backup-storage cifs iocharset=utf8,rw,credentials=login.txt,file_mode=0660,dir_mode=0660 0 0

then try

  mount -a

Another solution is to prefer [[wiki:ipv4_over_ipv6|ipv4 over ipv6]] and the dns name should work again.

===== CIFS: Status code returned 0xc000006d STATUS_LOGON_FAILURE =====
Error from ''journalctl -xe'':

  ...kernel: CIFS: VFS: \\uxxxxxx.your-storagebox.de Send error in SessSetup = -13
  ...kernel: CIFS: Status code returned 0xc000006d STATUS_LOGON_FAILURE

When trying to ''ls'' the directory the error is:

  ls: /mnt/backup-storage: Host is down

The above happened when using the Hetzner storage box. When using the IP address the mounting works. Another workaround is to leave the DNS name and lazy unmount and remount the cifs share e.g.

  umount -l /mnt/backup-storage
  mount -a

Try a couple of times above and then check with ''df -h'' and it should work again.

===== Hetzner storage suddenly stops working =====
Example:

<code>
root@host:~# ls -l /mnt/
ls: cannot access '/mnt/backup-storage': Host is down
total 0
d????????? ? ? ? ?             ? backup-storage


root@host:~# findmnt
...
└─/mnt/backup-storage          //u287957.your-storagebox.de/backup
                                           cifs        rw,relatime,vers=3.1.1,cache=strict,username=xxxx,uid=0,noforceuid,gid=0,noforcegid,addr=159.69.63.181,file_mode=0660,dir_mode=0660,

</code>

It might be that the IP address changed and in ///etc/fstab// you have domain set up like so

  //u287957.your-storagebox.de/backup /mnt/backup-storage cifs iocharset=utf8,rw,credentials=login.txt,file_mode=0660,dir_mode=0660 0 0

Try pinging the dns name:
  ~# ping -4 u287957.your-storagebox.de
  ~# ping u287957.your-storagebox.de

You should see that the IP changed. Now unmount and remount everything and it should fix it.

  umount /mnt/backup-storage
  umount //u287957.your-storagebox.de/backup

  mount -a
