Ombi requires refresh daily, how to automate?

Is there a simple cron job I can make to restart ombi every 6 hours? Currently it goes down about once a day for me and needs a refresh. Seems if I could just have the service refresh itself every 6 hours that would be an easier solution, however I don’t know enough to be able to do this.

0 */6 * * * systemctl restart ombi >/dev/null 2>&1

Perfect thank you
