How to fix a ZKTeco device that won’t connect
This applies to the Local Wi-Fi (LAN) connection, where the on-site phone or tablet running the RushFlow app pulls from the device. If it can’t reach your ZKTeco device, it’s almost always a network issue — the device and that phone must be on the same router, and the device’s IP address and port must be right. (If you use Cloud push (ADMS) instead, there’s nothing on-site to reach — check the device has internet and the correct RushFlow server address.)
Step by step
- Same networkConfirm the ZKTeco device and the on-site phone/tablet running the RushFlow app are on the same LAN/Wi-Fi (same router).
- Check the IP addressFind the device’s IP in its network menu and confirm it matches what you entered in RushFlow (HR → Attendance devices). If your network reassigns IPs, set a fixed one for the device.
- Check the portZKTeco devices use port 4370 by default — make sure that’s the port on the device and it isn’t blocked on the network.
- Power-cycle and retryRestart the device and reopen the RushFlow app, then try to connect again.
Frequently asked questions
Why can’t RushFlow connect to my ZKTeco device?
On Local Wi-Fi (LAN), usually the device and the on-site phone running RushFlow aren’t on the same router, or the IP/port is wrong. Put both on the same network, confirm the device IP, and use port 4370 (the default). On Cloud push (ADMS), instead confirm the device has internet and the correct RushFlow server address.
