Hi,
Please help check if the Android phone and the Tapo camera are connected to the same router's Wi-Fi. Please note that you can continuously watch the camera's Live View page only when your phone and the camera are under the same network.

If they are under the same network but you have the Continue prompt, please help check the following information.
1. Please describe your network diagram, such as the Internet cable--Wireless router)))(((Tapo Cameras, phones, etc.
Are the camera and phone connected to the same router's Wi-Fi or connected to different devices(such as router and AP/RE)?

2. Check if the phone that installed the Tapo app can ping the camera successfully or not.

3. Disable the AP isolation feature and lower the firewall level on your router for a try.

Best Regards
