I’m trying to use Tailscale to setup Hyperbackup from my onsite NAS to an offsite NAS. The problem I’m running into is when setting up the HyperBackup task. When I click login I get an error that says “Failed to connect to the backup destination” and then it gives me 5 things to make sure of.
I’ve confirmed the IP address is the correct one for the destination target from Tailscale’s dashboard.
I’ve confirmed Hyperbackup Vault is installed and running on the backup destination
I’ve confirmed the backup destination has proper network connection.
I understand I do not need to configure port forwarding on the destination router if I’m using Tailscale.
I’ve set up a firewall rule on the destination Synology that allows Hyperbackup Vault from my specific Tailscale IP. And I’ve set up a rule that allows Tailscale VPN through my specific Tailscale IP.
I’ve also enabled outbound connections from other things running on Synology by enabling TUN using the script provided on the Tailscale website on both the source and destination NAS.
Does anyone have any ideas on how to solve this?
