Tailscale guide

Watch your PC from anywhere with Tailscale

Tailscale gives your PC and phone a private, encrypted link that works from anywhere, as if they were on the same Wi-Fi. With it, SysWatch local mode works away from home: instant updates, nothing sent through the SysWatch cloud.

Tailscale is a separate product with a free personal plan. SysWatch does not include it and does not need your Tailscale password.

Set up, about five minutes

  1. PC: install Tailscale from tailscale.com/download and sign in.

  2. Phone: install Tailscale from Google Play and sign in with the same account.

  3. Check that both show Connected in Tailscale. Each device now has an address that starts with 100.

  4. SysWatch on the PC: choose Tailscale as the connection, on the first run or later in Settings. Tailscale runs on local mode, so a PC already set to Local works too.

  5. Open Pairing. Under addresses you should see one labelled Tailscale.

  6. SysWatch on the phone: scan the QR code.

Done. At home the phone uses your Wi-Fi address. Away from home, with Tailscale on, it switches to the Tailscale address by itself.

Good to know

  • Keep Tailscale switched on on the phone when you are out. If it is off, SysWatch shows “PC not reachable” until you turn it back on.
  • On Android, Tailscale counts as the phone’s VPN. Only one VPN can run at a time.
  • If you paired before installing Tailscale, scan the QR code again so the phone learns the Tailscale address.
  • No Tailscale address in the Pairing screen? Tailscale is not connected on the PC. Open it from the tray and sign in, then reopen Pairing.
  • The PC must be awake. Tailscale cannot reach a sleeping computer.
