I use the 3-2-1 backup rule. Two identical DS220+ Synology NASs are involved, one NAS is offsite.
I have been using Hyperback up on local NAS to backup on the remote NAS (one way direction) every morning 4am for a year now with no issues.
A few days ago, it stopped working and hoped the problem would go away but it wasn't it.
When I visit my local Hyperbackup, I see, Target-Offline.
I'll write out a few observations, hopefully someone can help suggest a fix.

- I am able to QuickConnect to the remote NAS and also use the [remote-server].synology.me to login as administrator.
- No changes have been made to hyperbackup on my local machine for a long time
- Strangely, I don't get a response when I ping [remote-server].synology.me but I do get a response when I ping [local-server].synology.me
- The remote hyperback vault is running with no apparent issues.
- The synology Firewall on both servers are off
- The remote-server has port forwarding set up for 6281
