    Give a minute, I have many storage boxes and sub-account and use them for Cloudron.

    This is working for me and has worked for years.
    Here is also my Hetzner overview of the storage box.

    If you'd like @ekevu123 we can take a look together.
    Send me a dm if want to do that.

    @BrutalBirdie it was just that he'd added a passphrase to the SSH keys 🙂

    @ekevu123 having done it a few times myself now (for backups and various volumes) it looked like you'd done everything right so that was the only thing I could guess it could've been - glad it was that and it helped 😊

    I use Cloudron with Gandi & Hetzner

      Yes, exactly, it works now!

      Maybe there could be a dedicated tutorial in https://docs.cloudron.io/backups/ as many people seem to use it as a backup provider. I had to look up a few other things in the process to make it work.

        I also used a passphrase the first time I had to setup hetzner storage via sshfs, for me it's a best practice so I always put a passphrase.

            Have the same issue, error logs seems to be the same pretty much:

            }
            

            SSH key comes without password, and I can connect via SSH - no problems:
            ssh -p23 u1212121@u1212121.your-storagebox.de -i hetzner

            I've tried to pick up systemd file for troubleshooting, but I didn't find any in the system - guess it's removed if no luck connecting.

            Any help would be much appreciated!

              @potemkin_ai Did you specify /home as Remote Directory?

                  @potemkin_ai Looks like it might be a networking issue. Is the storage box responding to a ping if you ping it from the server? The SIGTERM suggests the command timed out waiting for a response, indicating the storage device might be unresponsive or inaccessible.

                    @potemkin_ai
                    Be aware, Hetzner Storage Box via port 23 sshfs has fail2ban.
                    After some attempts you get blocked for some time.

                    @potemkin_ai can you test if these steps work:
                    https://forum.cloudron.io/post/105362
                    Test it locally and on your server.

                      Like I've told:

                      I can connect via SSH - no problems:
                      ssh -p23 u1212121@u1212121.your-storagebox.de -i hetzner

                      => not a networking issue and 23 port works fine.

                      Looks more like a SW bug to me: https://forum.cloudron.io/topic/13634/addmount.sh-script-error-prevents-sshfs-mount

                        @potemkin_ai can you these steps work:
                        https://forum.cloudron.io/post/105362

                        It looks like the following option is missing to make sshfs actually work with SSH keys authorization:
                        -o IdentityFile=hetzner_storage_box

                        But yeah - it works.

                        According to the Cloudron logs, the failure is happening not while trying to mount, but at the stage of mounting - as the parser fails to extract 'Where' (instead of just getting it as an input, for example).

                          and nc -vv u12121212.your-storagebox.de 23 from the server - does not

                          @BrutalBirdie , as stupid as it could be - I might get trapped with Hetzner's fail2ban - thanks for pointing that out.

                            It was not fail2ban - it was IPv6 connection which is failing, as IPv6 disabled (to ensure mail works well). Hetzner's supported provided a very quick and efficient verification / troubleshooting step: ssh -vvv -p 23 user@server - hope that will be of use for anyone else in the future.
