Hi, 
Typically, you can refer to the following instructions to troubleshoot if you fail to control the camera remotely.
What to do if I can't control my Tapo cameras on the Tapo app?
 

Please confirm the following information if the same phenomenon persists.
  1. What's the model number of your router? Do you have an internet connection when connecting to the router's Wi-Fi directly?
  2. Is the camera connected to the router's Wi-Fi directly, rather than an AP/RE? What's the LED status on the camera, such as solid red, flashing red, etc.?
  3. Please try to enable a hotspot Wi-Fi on your phone, factory reset the camera, configure it with another phone, connect it to the hotspot Wi-Fi, and then check if you can control it remotely. 
 

Best Regards
