The POS app seeks to connect to the Silver host to synchronize data between the device and the Silver host. This synchronization occurs at least every three minutes. The host status color indicates the ability of the device to connect to the Silver host.
With a host status color of green, you have an Internet connection, which allows the POS app to connect to the Silver host and synchronize data. You can also synchronize the data manually. Tap the cloud icon to display the connection status menu, and then tap Sync Now.
With a host status of yellow, the POS app may not be able to connect to the host. Check your WiFi settings.
With a host status of red, you do not have an Internet connection, which prevents the POS app from connecting to the Silver host. When the host status color is red, the credit processor status color is yellow or red, depending on your offline credit configuration. Even with a host status color of red, it is possible for your server status color to be green, if the POS app can connect to the server but not to the Internet. When your host color status appears red, check your WiFi settings and your Internet connection.
