Please check that your validator is attached to your node.
We recommend setting up a systemd service with an autorestart on boot (should you experience an unexpected power outage, this will ensure your validator restarts correctly).
Systemd will also ensure your validator keeps running when you exit your ssh session (
Ctrl-C) and/or switch off your laptop.
