If the camera reports a "Cloud service connection fail" error when you connect it, it means that the camera fails to build the connection with the cloud server.
- Please make sure that your Wi-Fi router is connected to an available network. You can try to connect the Wi-Fi to your phone, if you can normally browse the Internet, it means that the Wi-Fi works.
- If it is but the issue still exists, please restart your Wi-Fi router and try again.
- If the issue still exists after restarting the Wi-Fi router, it's very possible that there is some restriction(s) on the Wi-Fi router. In this case, you can try the below:
- Remove the restriction on the Wi-Fi router: enter the router's admin address in the browser address bar (usually the admin address will be written on the router‘s body) > enter the admin password to go into the admin site > click LAN > click DHCP Server > Set Server 1 as 8.8.8.8 and Server 2 as 8.8.4.4 under "DNS and WINS Server Setting".
- If possible, reset and re-configure your Wi-Fi router.
- If possible, try to connect the camera to another Wi-Fi.
In addition, you can also try rebooting the camera to add it back to the WiFi network.
