The POS is offline or "can not communicate with the others

What the pink terminal name and the red sign-in warning mean, what keeps working without the internet, and what to do.

There are two different signs:

If you see the red warning

  1. Check the terminal's network: is the cable plugged in, or is Wi-Fi connected?
  2. Use another terminal for now. The warned terminal still works, but its orders and sales won't show on the other terminals or in closeout numbers until it reconnects.
  3. Once it's back on the network, the warning clears by itself and its sales catch up.
