Most likely causes: Changes on network or configuration, network/router issue.
Check that the iPad and Eftpos are on same network. Look in iPad settings > Wi-Fi
Ensure you are entering the IP address in this format eg.- 192.168.1.345 - remove any extra digits after the last number.
Make sure the IP addresses on the Eftpos terminal and posBoss Eftpos settings match - enter in the address showing on the terminal into posBoss
Close and restart the posBoss app.
Reboot both iPad and Eftpos terminal (remove terminal battery if possible and replace)
Have you swapped to a new Terminal? You may need to do a full Delete and Reinstall of posBoss to refresh the settings and allow you to set up again.
Are you using an S920 or S800 Terminal? - these can show an error that they are not compatible but should still work. Test it to see if it is working and ignore the error.
Is the Eftpos button no longer there?
Is the Eftpos transaction successful but posBoss doesn't close it off?
Most eftpos issues that occur between posBoss and the Smartpay device are caused by underlying issues on the Network or Router. Rebooting the router may help in the short term but if intermittent connection issues persist, check out the following article:
Try restarting your router. Turn off the router for a full minute then restart it. Leave it for another couple of minutes. Please note: If you have Star printers, the IP address may have changed so you may need to Search for printers again to locate them - in the posBoss printer settings.
Have there been any recent changes on your network? You may need to contact your IT provider to assist.
If none of the steps above work, it may pay to contact your Eftpos provider:
