Hi,
In this case, please check if you can manage the Tapo C200 on the Tapo app, such as check if the Tapo C200 shows online on the Tapo app, and check if you can watch its live view page, etc.
If not, it's suggested to double confirm if the Router is still working fine. If the router is not working, reboot the router or contact router support for a try.
And also please help confirm the LED status on the camera to judge if the camera is working.

If the router is working fine and the camera showing online on the Tapo app, but stop recording, please refer to the link below to check if the motion detection settings are correct.
