Hi,
You can try the following steps for the reported case and check if they help.
1. Refer to the instructions below to factory reset your camera, and ensure your reset operation is correct.
How to reset my Tapo camera?
 

2. If the LED changes to flashing amber and green, you can try to reconfigure the camera.

If the LED does not change, you can try the following steps.
1) Make sure the internet is stable and the router has a strong signal.
2) Power off the camera.
3) Move the camera closer to the router and power on the camera.
4) Wait for around 10 minutes, and check if the camera will work.

Btw, is your Tapo C320WS's hardware version V1 or V2?

Best Regards
