WiFi connection failed.

Make sure the connected Wi-Fi is on the 2.4GHz band, as some cameras do not support 5GHz Wi-Fi networks.

Avoid using special characters in the Wi-Fi name or password (it is recommended to use alphanumeric combinations).

Ensure the correct SSID and password are entered in the "WIFI STA Mode" settings.

After performing the above steps, the Wi-Fi connection should typically be successful.
