@ErikDerBezwinger I can't initialize the repo on the storage box, with this error every time:
`Remote: ssh: connect to host [ID].your-storagebox.de port 23: Connection timed out`

I already tried everything imaginable, from adjusting the firewall on both Hetzner and the machine, adjusting router configurations, etc.

I've been trying to make this work for almost a year at this point, and it never works no matter what, which is why I decided to look for a different backup system

@davidbures @ErikDerBezwinger Connection timeout sounds like you do not reach the Storage Box and the connection is dropped somewhere in front of it. Some ISP block port 23 as it was the default port of telnet.

To test it you can run a mtr (kind of traceroute) via TCP against port 23 of the Storage Box.

mtr -T -P23 -r -c20 <username>.your-storagebox.de
