How do I tell if my always-on box is dead or just offline on Tailscale?

Three different problems feel the same from the couch. Dead hardware: power’s off, disk full, or OS wedged. Nothing on that machine answers. Flaky path: the box is fine but shop Wi‑Fi or the ISP isn’t. Tailscale auth dead: the machine is on and you can log in locally, but remote access fails because the node needs a fresh login or was disabled. Check power/local life first, then whole-site internet, then auth.

Does a green Tailscale admin dot mean I’ll get alerted?

No. Opening the Tailscale admin and staring at a green dot is not the same as getting told when the box dies. You want an email when the machine stops checking in (for example Healthchecks.io). Prove it: unplug once on purpose, wait for the mail, plug it back in. That email only means the box stopped checking in. It does not prove Tailscale or a camera app is healthy.

Will this work with Ring / cloud cameras?

No. Cloud cameras aren’t the box; you need something you can install Tailscale on (a shop PC, Pi, or NVR/PC you admin).

When the box goes dark

You’ve got a PC or a Pi that runs cameras, files, whatever. It’s supposed to stay on. Then one night you can’t get in, and you don’t know if the machine died, the Wi‑Fi blinked, or Tailscale just logged out.

I’ve driven across town for all three. Only one of them needed the drive.

Three failure modes: dead hardware, flaky Wi‑Fi or network, Tailscale auth dead

Same feeling, three different problems

The box is dead. Power’s off, disk’s full, OS wedged. Nothing on that machine answers. Rebooting your laptop doesn’t help. Waiting doesn’t help.

The path is flaky. The box is fine. Shop Wi‑Fi or the ISP isn’t. It works, then it doesn’t, then it works again. Classic “after dinner” problem.

Tailscale auth is dead. Machine’s on. You can sit in front of it and log in. From your phone off-site? Nothing. The node needs a fresh login or got disabled.

If you treat all of those like “the VPN is broken,” you’ll reinstall Tailscale until you’re mad and still not know whether the hardware is alive.

What I do before I leave the couch

Power / local life. Lights? Local screen? Can someone on site touch the keyboard? No → assume dead box until proven otherwise.
Whole site internet. Do phones on the shop Wi‑Fi fail too? Yes → fix the path first. Don’t blame Tailscale.
Box alive locally, remote dead. That’s usually auth. Sign Tailscale back in on the machine that’s still running.

The part people skip

Opening the Tailscale admin and staring at a green dot is not the same as getting told when the box dies.

I want an email when the machine stops checking in. Not a dashboard I forget to open. Unplug it once on purpose, wait for the mail, plug it back in. If that loop doesn’t work, you don’t have a dead-man. You have a hope.

That email only means the box stopped checking in. It does not prove Tailscale is healthy. It does not prove the camera app is fine. It’s one signal. Use it with the three cases above.

What this is not

Not Ring / cloud cameras you can’t install software on (wrong box)
Not opening ports to the whole internet “just for a minute”
Not me watching your stuff at 2 a.m.

Access Pack ($99)

Same steps I use: Tailscale on a box you control, reach it without WAN port-forwards, Healthchecks email when it’s actually gone, prove-it unplug, break-glass notes.

Access Pack ($99)

ZIP. Your accounts. Not a managed service. Not 24/7. Tailscale stays yours.
