Yes, this job running is crucial to save data to the database. I’m not sure why it’s not running, but we are investigating now.
As @noahsprent mentioned, on your leader, check the status with:
sudo systemctl status pioreactor_startup_run@mqtt_to_db_streaming.service
And if it says anything other than (running), try to restart it:
sudo systemctl restart pioreactor_startup_run@mqtt_to_db_streaming.service
