Hi everyone! I’m offering this tutorial to be alerted when your Gladys is no longer online, for example in case of hardware issues or a crash. On my side I use a (free) service called [https://healthchecks.io/](https://healthchecks.io/) which allows you to create a « dead man’s switch ». Concretely, Gladys will contact this site at regular intervals, and if Gladys does not check in, the site will know that Gladys is no longer available and will notify you. I created a healthcheck on their site : ![Screenshot 2024-10-28 at 17.30.31](https://gladys-assistant-community.b-cdn.net/uploads/default/original/3X/f/0/f0760923cc6ae97cdecaba2686632762dcf3901c.jpeg) I retrieved the URL. Then I have a scene in Gladys that pings the healthcheck every 5 minutes : ![plus.gladysassistant.com_dashboard_scene_ping-healthcheck](https://gladys-assistant-community.b-cdn.net/uploads/default/original/3X/4/c/4c4d1c07c8a1a05a3aeccd9f6bdd38df36891efb.png) If one day Gladys or my internet is down, I see it immediately — I receive an email; it’s possible to get notifications on lots of services (WhatsApp, Telegram, ntfy, etc.). I sometimes see disconnections when my internet box updates (usually around 2–3 AM). Very handy! ---

Hello, the request from Firefox works but not from HealthCheck with the message below. What should I do?

@thierry06 are you sure about the URL? I just tested it on my end, and it still works perfectly: ![Screenshot 2025-03-24 at 09.03.53](https://gladys-assistant-community.b-cdn.net/uploads/default/original/3X/d/9/d9bdb0ee2c421084212e6184c1b3da3fe8ab7f62.png) ---
