Hi,
You can refer to the link below to reset the camera, and then reconfigure it for a try.
Reset the camera to factory default settings. 

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

And if the problem remains, please help confirm: 
1. Please send me a screenshot of the error message that appears when configuring the camera.
2. Please let me know the troubleshooting you have done.
3. Check if your phone and the camera are connected to the router's 2.4G Wi-Fi rather than 5G.
4. Check if the Wi-Fi name and password include special characters, such as @, &, etc. If yes, change the Wi-Fi name or password for a try.
5. Connect the camera to a hotspot Wi-Fi from your phone and check if it will connect successfully.

Best Regards
