In some cases, card terminals may display messages regarding their connection. To ensure that your card terminal has a stable connection, follow these steps:
Messages that may appear on a card terminal and what they mean:
If your local network is temporarily unstable or loses connection, the Onslip app and the card terminal may lose contact with each other. Depending on which terminal you’re using, you may then see an error message, such as:
- “Kassan tappade anslutning till kortterminal”
- “Lyckades inte få respons från betalterminal”
- “Terminal ej funnen”
- “Terminalen svarade inte i tid”
Here are a few simple steps to quickly restore your connection and optimize your network for more stable performance in the future.
How to optimize the connection (Step by step)
1. Check that the devices are on the same network For the Onslip app and the card terminal to communicate smoothly, the devices must be connected to the same local network. Please read our guide on how to set up a stable network environment.
- Tip: Use a static IP address. We recommend assigning the card terminal a static IP address in your router. This way, the Onslip app will always know exactly where the card terminal is located, even after a power outage or router restart. If the network has been restarted and you are not using a static IP, the card terminal may have been assigned a new address. In that case, compare the IP address in the card terminal with the one entered in the Onslip app to ensure they match.
- Reconnect the card terminal: Do the devices need to discover each other again? Follow our quick guide to reconnect the card terminal.
2. Use only one network connection at a time. For the best possible stability, only one type of connection should be active on your hardware. If both Wi-Fi and an Ethernet cable are active at the same time, the operating system may become unsure of which path to use for sending data. Therefore, make sure to turn off the device’s Wi-Fi if you’re using a cable (and vice versa).
3. Network ports (Applies only to strict firewalls). If you are on a high-security network (for example, within a municipality or a large company), certain digital “paths” need to be opened so that the card terminal can communicate with the banks. If you have an IT technician managing the network, ask them to ensure that the following ports are open:
- Port 443/TCP
- Port 53514/UDP
-
For Westpay card terminals, the following also apply: IP-adress 185.27.171.151 on port 55102/TCP och 55101/TCP.
Tip: Give the router a fresh start Just like any technical equipment, a router benefits from being restarted occasionally. A simple restart of the router often clears up temporary network glitches and gives your devices a fresh, strong connection.
If the message persists after following the steps above, try restarting the card terminal. Of course, you’re always welcome to contact our support team, and we’ll be happy to assist you further!
