Backup form Qnap to Synology NAS


i try to make backupf from my Qnap NAS to a Synology NAS.
For this i enabled SSH on the Synology, but i dont know what path i need to enter in duplicati to make backups to that device.
All i tried until now ended in getting a error, that there can’t be an connection.
With Putty and WinSCP i can connect wihtout problems.
The servernname should be clear, but im unsure how the path should look like.
I guess it must be something like
But Connection test fails.

Thanks for any help.

Try /var/services/homes/username. Not sure but was something like that.
