'Failed' prompts on the Loona screen and returns to the QR code interface after 3 seconds:
It means Loona failed to connect to Wi-Fi successfully. Please check whether the number of devices connected to your router has reached the upper limit, and whether you have set anti-chafing network, anti-strange device connection and other functions for the router. If yes, please set the router to trust Loona device and connect again. The specific process can be found here: Router anti-squatter and device management settings, (different router settings may be slightly different)
