Stop working. Everything is connected and correct( green light). After a while stop working and show me that message: inCarDoc Failed to connect to WiFi reader 1. NB! Make sure you're connecting to OBD-II WiFi reader. 2. Make sure OBD-II WiFi reader is in the car's OBD-Il slot and also is displayed in the Wi-fi list of connections.

When you encounter a "Failed to connect to WiFi reader" error message while using InCarDoc, it usually means that the app is unable to establish a stable connection with the WiFi reader device that is connected to your vehicle's OBD port.
