Hi,
If you fail to configure the Tapo camera, you can refer to the link below to troubleshoot.
What should I do if I fail to configure Tapo Camera?

If the problem remains, please help confirm the following information.
1. Check the version of the Tapo app, and ensure the Tapo app is up to date.
2. Move the camera close to the router, ensure no special characters(such as &, #,*, etc.) in the password, and please help check the wireless security type, change the security type to WPA-PSK or WPA2-PSK if possible.
3. Please disable the 5G Wi-Fi on your router, ensure your phone is connected to the router's 2.4G Wi-Fi, and no VPN program running on your phone when configuring the Tapo camera.
4. Please check if your router has special settings, such as MAC filtering, parental control, etc., disable them for a try if there are.
5. Connect the Tapo C320WS to another Wi-Fi network, such as the hotspot Wi-Fi from your phone, and check if it works.
Best Regards
