Hi,
It seems the camera is connected to the router's Wi-Fi name but not connected to the internet or our cloud server, so you can't control it remotely. In this situation, changing your router's DNS server may solve the issue, but if you can't do it, you can try other suggestions in the following instructions first.
What to do if I can't control my Tapo cameras on the Tapo app?
 

Please confirm the following information if you need further assistance.
1. What's the model number of your router? Do you have internet when connecting to your router's Wi-Fi?
2. You can try to enable a hotspot Wi-Fi from your phone, factory reset the camera, reconfigure it to connect to the hotspot Wi-Fi on a different phone, and then check if you can control it remotely.

Best Regards
