ScriptThe machine does not connect — check these first
| What you see | The fix |
|---|---|
| HTTPS is ON on the machine | Turn HTTPS OFF. With port 80 a secure connection cannot work. The machine calls in within a minute. |
The machine's IP address is 0.0.0.0 | The machine is not on the network. Check the cable or join the WiFi (Menu → Comm → Ethernet or WiFi). |
| Server Address is empty, or the port is not 80 | Someone changed the settings. Type the five settings again. |
| The keypad cannot type a dot (.) | Turn Enable Domain Name OFF and type your server's IP address in the four boxes. |
| It shows up, but punches do not count | New machines wait as Pending approval. Open Devices and press Approve. |
| Old punches are missing | Open the machine on the Devices page and press Re-send all stored punches. Nothing is doubled. |
| Punch times are wrong | Set the machine's date and time (Menu → System → Date/Time). |
| A punch shows a PIN but no employee | Open Employees → Unmatched PINs and link the PIN to an employee. |
