Cannot add Hetzner Storage Box via sshfs

[ekevu123]

I have set up a Hetzner storage box and I am trying to use it as the main backup location for Cloudron, but it fails with this error:

Failed to mount (inactive): Could not determine mount failure reason.

This is what I have done:

1. I have created an ssh key on the cloudron server
2. Added it to Hetzner into .ssh
3. Connected to Hetzner via "ssh -p 23 uXXXXX@uXXXXX.your-storagebox.de"
4. Verified that /home is writable

For the cloudron backup setup:

• hostname: USER.your-storagebox.de
• remote directory: /home
• port: 23
• user: Hetzner user id
• private key inserted
• use hardlinks checked

This was in the Cloudron server logs:

A similar thread recommended to check whether unbound was working, which I checked like this:

systemctl status unbound

I would appreciate assistance with this as the error doesn't give me anything else, it seems.

@ekevu123 said in Cannot add Hetzner Storage Box via sshfs:

created an ssh key on the cloudron server

Did you remember not to use any passphrase?

[ekevu123]

No, I didn't, that solved the issue!
And I just came to the same conclusion and came here to update this thread. Thank you for pointing this out!

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

[ekevu123]

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.

[BrutalBirdie]

Ahhh.
I did not expect that
