Make sure the Onslip app has a stable connection to your network
Onslip is designed to handle temporary network outages, but requires a stable internet connection to sync your sales in real time. When the device is searching for a network, status messages will appear on the screen to inform you of the situation.
What do the status messages mean?
If you see any of the messages below, it means the register is waiting to regain its internet connection. Please note that your data is secure in the meantime.
- Status: Error with cloud-based control unit – The register is functioning, but the system is waiting to connect to the control unit via the internet to record the transaction.
- Status: Offline / Data update failed – Synchronization is paused. The device needs to connect to the network to complete the upload of its latest data.
- Status: Transaction queue enabled / full – This is a built-in security feature! Your sales are safely saved locally and will be uploaded automatically as soon as the network is back.
- Status: Not allowed, online only – Certain specific payment methods or features (e.g., gift cards) require an internet connection and are waiting for the connection to become active again.
- Status: User inactive (The user has not logged in online in the last 30 days) – The system needs to establish a temporary connection to the network to verify your user profile.
- Status: Server not responding or Failure server.abort: XHR aborted, state 4 The POS has temporarily lost connection to the network, and a local request (e.g., a payment) has been aborted. This is rarely due to an actual server error, but is usually caused by one of the following:
- Network issues: The Wi-Fi or network cable has lost connection. Solution: Check cables and network.
- Timeout: The response time from the network was too long. Solution: Try again.
- Manual interruption: Someone has clicked “Cancel” or switched screens in the middle of the process.
- Blocked: A local firewall or security program is blocking the traffic.
Why do these messages appear?
For the automatic flow to work optimally, an uninterrupted communication path is required. When the status messages above appear, it is usually due to external factors:
- The hardware is searching for the network: The device may have lost contact with your router or access point, preventing it from connecting to the internet.
- The local network has no internet connection: Even if your hardware has a perfect connection to the router, the actual internet service from your provider may be temporarily down.

Article 2: Verify Internet Connection for the Z Model
If you encounter any of the status messages mentioned above, follow the steps below to verify the Internet connection for your Z model hardware.
Step 1: Restart the equipment
- Turn off the Z-model hardware: Hold down the power button on the left side until the screen turns off.
- Turn off the network: Turn off the modem and routers. Wait 30 seconds.
- Restart in order: First start the modem, wait one minute, then start the router, wait one minute.
- Restart the Z-model hardware: Power it on, log in, and try again.
Step 2: Check the cables
- Make sure the network cable is securely plugged into the port labeled LAN on the bottom of the Z-model.
2. Make sure the other end is plugged into a LAN port on your router.
Step 3: Cable Connection Settings (Ethernet)
-
Tap the Home button (the house icon at the bottom left).
-
Open the Settings app.
- Turn off Wi-Fi. Then select More... in the list on the left.
- Go to Ethernet and make sure Use Ethernet is checked.
- Check if an IP address is displayed on the screen.
This means the cash register cannot contact the router, or modem, it is connected to.
In most cases this means the cable is not connected properly. Once again, make sure the cable is in the correct plugs in both the cash register and the router. See reference pictures above.
If the cable is connected properly and you still cannot get an IP address you may need to restart your cash register again.
Hold down the power button on the left side of the cash register until the screen turns off with a clicking noise. Wait a few seconds and start the cash register again, the same way.
When the cash register has started again, check if it's getting an IP address now.
If it's still not getting an IP address after the restart, the network cable may be broken. Try connecting a new cable. Also try a restart again, as well as unchecking Use Ethernet and check it again.
If it still isn't getting an IP address after this then the network connector on the cash register may be damaged. This is especially probable if there have been lightning strikes in the area.
Check whether or not you can connect over WiFi instead, if you do not want to exchange your cash register. Note that our warranty does not cover natural disasters such as lightning strikes.
Good. This means the cash register can connect to your router, but for some reason cannot connect to the internet.
Follow the network cable from the cash register to the router itself.
Make sure the router has a cable in the WAN port. (If you have a white TP-Link router from Onslip, the WAN port is the blue connector.) This cable needs to be connected to your modem or fiber connection in the wall.
If the cable is connected properly the internet symbol will glow or blink green.
Make sure the WAN cable is connected properly and everything is green. If the internet symbol glows orange the router cannot access the Internet. In that case, check your modem and contact your internet service provider.
Restart your router and eventually modem, to be on the safe side. Try the cash register again to see if it works now.
If it still doesn't work, it may be that the cash register's date and time is incorrect. It might not seem important, but it is important that the cash register, and internet services, are agreed on the date and time.
Press the home button (the button in the middle, in the bottom left of the screen that looks like a house).
Enter the app Settings.
In the list to the left, scroll down to Date & time.
Make sure the cash register's time zone, as well as date and time are the same as reality. If not, try unchecking Automatic date & time and check it again. Alternatively, set date and time manually.
Try again after this.
If it still doesn't work, your internet service provider may have issues with communication right now. An error report may need to be filed, it could be that SSL encrypted traffic cannot be sent at this time. Try connecting to a phone hotspot via Wi-Fi temporarily to see if that works.
Press the home button (the button in the middle, in the bottom left of the screen that looks like a house).
Enter the app Settings.
Choose Wi-Fi in the list to the left and make sure you are connected to the proper network. If you are using a white TP-Link router from Onslip the network will be named Onslip. The password is on the bottom of the router.
It may help to forget other networks that are Saved. This is because the cash register can otherwise jump from network to network which may cause problems.
At the same time, make sure the router has a cable in the WAN port. (If you have a white TP-Link router from Onslip, the WAN port is the blue connector.) This cable needs to be connected to your modem or fiber connection in the wall.
If the cable is connected properly the internet symbol will glow or blink green.
Make sure the WAN cable is connected properly and everything is green. If the internet symbol glows orange the router cannot access the Internet. In that case, check your modem and contact your internet service provider.

If it still doesn't work, your internet service provider may have issues with communication right now. An error report may need to be filed, it could be that SSL encrypted traffic cannot be sent at this time.
Try connecting to a phone hotspot via Wi-Fi temporarily to see if that works.
If it still doesn't work even with a mobile hotspot, it could be that the Wi-Fi transceiver in the cash register is performing badly. If at all possible, connect the cash register by cable.
Put a network cable into the cash register.
It should be in the LAN connector on the bottom of the cash register.
The other end of the network cable needs to be in a router with access to the Internet. In most cases the connector is named LAN 1, 2, 3 or 4.
Press the home button (the button in the middle, in the bottom left of the screen that looks like a house).
Enter the app Settings.
Be sure to turn off Wi-Fi. Once Wi-Fi is off, choose More... in the list to the left and make sure Use Ethernet is checked. See if you are getting an IP address that isn't 0.0.0.0
You are now connected via cable.
The first thing we do is restart all network equipment and then the cash register.
Yes, that sounds like a tired cliché, but you would be surprised how often it actually works.
- Turn off the cash register by holding the power button on the right side. A box will show on the screen, choose to shut down the cash register. Also turn off any routers or modems you have.
- Wait approximately 30 seconds.
- Start the modem, or router, that is the first link in the chain. The equipment that first receives the internet signal, that is.
- Wait a minute so you see it has started up properly.
- If you have several routers connected, start them too. Just as with the modem, wait a minute until it has started properly.
- Start the cash register now. Log in to Onslip like you usually do and try it again.
Check firstly if you have a network cable in the cash register or not. It should be in the left LAN connector on the back of the cash register.
The other end of the network cable needs to be in a router with access to the Internet. In most cases the connector is named LAN 1, 2, 3 or 4.
