[homeassistantlocal-beep]

Description

Unable to connect to Tapo: Cameras Control controller: PyTapo KLAP Error #3: ('Device connection error: XXX.XXX.XXX.XXX: Server disconnected', ServerDisconnectedError('Server disconnected'))

Reproduction Steps

1. Install Tapo: Cameras Control integration (version 7.1.3) via HACS.

2. Go to Settings → Devices & Services → Add Integration.

3. Select "Tapo: Cameras Control".

4. Enter Tapo account email and password.

5. Enter camera IP address (192.168.0.121).

6. Complete setup.

7. Integration attempts to connect.

8. Error appears:

   PyTapo KLAP Error Invalid Config #3:
   ('Device connection error: 192.168.0.121: Server disconnected',
   ServerDisconnectedError('Server disconnected'))

Additional notes:

• Camera model: Tapo C206
• Camera works correctly in official Tapo app.
• Camera works with official Home Assistant TP-Link Smart Home integration.
• Camera and Home Assistant are on the same LAN.
• RTSP works correctly.
• Factory reset did not resolve the issue.

Expected behavior

Camera should connect locally via KLAP like other supported Tapo models.

If applicable, add error logs.

Additional information

Network Setup

• Camera and Home Assistant on same LAN
• Static IP assigned
• No VLAN isolation
• No guest network
• Port 554 open
• RTSP works correctly

What I already tried

• Factory reset of the camera
• Reboot router
• Reboot Home Assistant
• Reinstall integration
• Re-enter credentials
• Close Tapo mobile app completely
• Assign static IP
• Test connectivity (ping OK)

Actual behavior

Handshake starts, but the camera immediately disconnects.
Server closes connection.

[JurajNyiri]

Always use "admin" as username for cameras. Cameras do not use klap protocol.

[homeassistantlocal-beep]

I am using only local camera credentials.

Configuration details:

• Username: admin
• Password: camera device password (not Tapo cloud account)
• No Tapo cloud credentials used

The camera is a Tapo C206.
Firmware version: 1.2.1 Build 250919 Rel34131n

Despite using only local credentials, the integration still throws:

PyTapo KLAP Error #3:
('Device connection error: 192.168.0.121: Server disconnected',
ServerDisconnectedError('Server disconnected'))

The handshake seems to start, but the camera immediately closes the connection.

Additional info:

• Camera works via RTSP
• Camera works in official Tapo app
• Official TP-Link Smart Home HA integration works
• Same LAN, no VLAN, no isolation
• Static IP assigned
• Factory reset did not help

It looks like the integration is still attempting KLAP or the firmware is rejecting local authentication.

Describe in detail each step of adding the device, what you see and what is the result and please enable and post debug logs.

[JurajNyiri]

I think I know what is the issue here. When you reach cloud account step, you enter wrong password. Then it gives you an option to change username. Do not do that, as I said, you must use admin with your cloud passowrd, not local rtsp account.

[homeassistantlocal-beep]

Issue resolved.

What fixed it:

1. I first configured the camera using a third-party Tapo mobile app.
2. After the camera was fully set up and working, I then enabled/added the local camera account (admin + device password).
3. After that, Tapo: Cameras Control was able to connect correctly and the KLAP error disappeared.

Before initializing the camera through the third-party app and then enabling the local admin account, the integration always returned:

PyTapo KLAP Error #3 – Server disconnected.

It seems the local authentication service was not properly active until the camera was fully initialized and the camera account was explicitly enabled afterward.

Now everything works correctly.

[JurajNyiri]

The LLM you are using to generate these messages will confuse other users reading this as the steps you described are incorrect.

1. admin + device password will never work, you use your cloud password
2. no klap protocol is being used

The error is no longer happening because you started using admin username with cloud password as I described above.

[homeassistantlocal-beep]

Thank you for the clarification.

You are correct.

After reviewing the configuration, the integration works when using:

Username: admin
Password: Tapo cloud account password

The issue was caused by using the wrong credentials (device password instead of cloud password).

Thank you for the explanation.
