Phenomenon Description:

The Tapo hub H200 is working fine, but an error message "Connection Failed" appears on the Tapo app when adding the above cameras to the hub.

Troubleshooting:

1. Ensure the camera/doorbell and hub have the same region code. 
You can check the labels on the hub and camera for it. If they don’t have the same region code, they can’t work together. Please avoid purchasing the camera/doorbell and hub separately from different countries. We recommend buying a kit that includes both the camera/doorbell and the hub together.

2. Check the LED on the Tapo H200, and ensure it has a solid green light, which means it’s configured successfully. 

If your Tapo H200 is not configured successfully, refer to the instructions below to troubleshoot.

3. Check the LED on the battery-powered camera, if the LED is not flashing green and red, reset it first.

4. Reboot the Tapo H200, move the camera close to the hub, and reconfigure the camera.

5. Place C420 and H200 in another location for configuration if the problem remains to avoid possible wireless interference in the original location.
 
If the camera still fails to pair with the hub, please help collect the following information and update it on this thread for further analysis.
1. The LED status on the Tapo H200 and the camera when you see the error message.

2. Send us the MAC address of the Tapo H200 & camera and your TP-Link ID via a private message.

3. Confirm whether the problem occurs when starting to use the camera. Or did the camera work before?

1) On your Tapo app>tap your Tapo hub>go to its Device Settings>Diagnostics page to turn this feature on.
2) Ensure your phone and the hub are connected to the same router, try to reconfigure the camera via the Tapo app.
