Has the connection with your terminal been lost after a software update?
You can resolve this by following the steps below:

1. Search in Windows for 'Allow an app through Windows Firewall'
2. Look for all entries named 'Win32Bridge' and enable both Private and Public for these items.
3. Click 'OK' at the bottom of this window.
4. Restart your POS application.
5. If you receive a Windows Firewall notification, enable both Private and Public networks and click 'Allow'.
