**Description**  
I erroneously thought I needed to update my SDK version, but since doing that I am still receiving an error code of 10 when joining a meeting from my SDK supported application. I decided to make a new app to use new authentication keys and I am now receiving an error code of 65535 even though the app is activated. I need the application back up and running but currently its down.

@chunsiong.zoom , any ideas?

**Which Windows Meeting SDK version?**  
zoom-sdk-windows-5.17.6.31095

**To Reproduce(If applicable)**  
It is localised to my application but:

- Create a new application
- Publish and activate the application
- Input the sdk keys into the sdk\_init\_auth\_ui.cpp (roughly line 190)
- Build an x64 release version
- Try to join a meeting and an error is received. Using the new credentials = 65535, using the old credentials = 10.

Error code 65535

Error code 10

**Troubleshooting Routes**

- Updated the SDK
- Attempted using different SDK authentication keys
- Consulted forums

**Device (please complete the following information):**

- Device: Custom PC (Nvidia GPU, Threadripper CPU)
- OS: Windows 10

@josh.perrott-hodgson

are you using a generated token using SDK Key and SDK Secret in this method?

```auto
void CAuthSDKUIGroup::DoAuthBtnClick()
{
	if(NULL == m_editSDKJWTToken)
		return;
	std::wstring strToken = m_editSDKJWTToken->GetText().GetData();
	if (strToken.size() > 0 )
	{
		ZOOM_SDK_NAMESPACE::AuthContext param;
		param.jwt_token = strToken.c_str();
		if (ZOOM_SDK_NAMESPACE::SDKERR_SUCCESS != m_AuthSDKWorkFlow.Auth(param))
		{
			if (m_mainFrame)
				m_mainFrame->ShowErrorMessage(L"auth sdk failed");
		}
		else
		{
			m_mainFrame->SwitchToWaitingPage(L"waiting auth result...", true);
		}
	}
}

```

Yes this is correct. The token used when the error\_code=10 is produced is from an old app that has been developed. I created a new app and used the new credentials as I thought perhaps the SDK key may be tied to the older version of the SDK, this consequently produced the error\_code=65535.
