The terminal and the POS each need their own connection, so this is nearly always a network fault rather than a fault with either device.
Check in this order
- Internet on both devices. The terminal and the POS each need a connection.
- Restart the terminal.
- Restart the POS app.
- Restart the router, if other devices are also affected.
If it worked yesterday and doesn't today
Something on the restaurant's network usually changed — a new router, a power cut, or another device taking an address. This is the most common cause. Restart the router first.

The terminal model, whether other devices are online, and whether anything changed in the restaurant's internet setup. Contact support.
