Since updating to DSM 7, when opening HyperBackup all of my targets were stuck on “Connecting” which eventually lead to the dreaded “Offline” state. What fixed this behaviour for me was to disable IPv6 altogether on both of my LAN interfaces, like so:
- open Control Panel and select Network and the Network Interface tab
- select LAN 1 or LAN 2 (whichever is under use, or do it for both)
- click Edit
- select the IPv6 tab then set IPv6 setup to “Off”
- restart the Synology NAS
Now if you open HyperBackup your targets should all be green!
