Why does the APP prompt that the connection has timed out when connecting the Xiaomi Smart Ceiling Light D20?

If the APP prompts that the connection has timed out, please refer to the following to troubleshoot:
1. The Wi-Fi password is incorrect. It is recommended to reset the light and enter the correct Wi-Fi password;
2. The network signal is not good. It is recommended to keep the lamps closer to the router while ensuring a good network environment. And then reconnect several times.
