Hello, I install crontab-ui with npm on my debian 11(DietpiOS) server on miniPC x64. I set rsync to backup home folder on usb connected HDD. Everything works OK. Next I want to make backup of home folder on other device. I sett ssh keys and try that command: rsync -avz --exclude=.cache dietpi@192.168.0.111:/home/dietpi /mnt/Toshiba/Backup/dietpi-laptop/home It works perfect in terminal but when I try it in crontab-ui it failed:

Tue Nov 29 11:47:05 CET 2022
Host key verification failed.
rsync: connection unexpectedly closed (0 bytes received so far) [Receiver]
rsync error: unexplained error (code 255) at io.c(228) [Receiver=3.2.3]

Regards.

OK, I exchange ssh keys as root.
