websockify logs "Openening socket failed" and calls sys.exit() when its port is taken, so novncd ended with status 0. Under systemd the unit then counts as stopped, not failed: Restart=on-failure does not start it again, systemctl --failed does not list it, and VNC consoles stay down until someone starts it by hand. novncd now ends with status 1 there.
