→ Common issues
| Issue | Solution |
|---|---|
| Test communication fails | Check that Modbus is enabled on the charger and that the charger was reset (Point 3.1). Check the IP address and the Modbus unit ID (Point 5.2). |
| Open configurator does not open or stays empty | The tunnel is not active yet. Wait about 30 seconds and check that the controller is online. |
Login with admin is rejected |
The password was changed during installation. Ask the installer. The Reduxi account password does not work here. |
reduxi.local does not load |
Your device is not in the same network as the controller. Use the IP address or the tunnel connection. |
| Communication test fails, device shows offline | Check reachability, IP address / port / unit ID, and that the protocol is enabled on the device. |
