Nothing strange. I encountered the same problem on my Viva (KN-1913).
I installed the ssh component, but I couldn't connect via SSH to my Keenetic Viva. I rebooted it several times, but that didn't help.
I scanned its ports, and port 22 was closed. I connected to it via telnet and checked the running services using the show processes command. I saw the following:
object:
id: SSH server
state: STOPPED
service:
configured: yes
alive: yes
started: yes
state: STOPPED
Well,
service ssh
system configuration save
solved the problem, the SSH service started.
