Hi! I’ve been using the zoom electron SDK successfully for several days. Today, suddenly, I started getting the following error when I do the SDK authentication: **[17848:1116/115434:ERROR:webrtcsession.cc(1226)] ConnectDataChannel called when data\_channel\_ is NULL.** The SDK authentication call causes the **apicallresultcb** callback to be called with the  **apiname** of **SDKAuth** and the ret value of **SDKERR\_SUCCESS.** The **SDKAuthcb** callback also gets called and the status it receives is  **AUTHRET\_SUCCESS** When this happens, the system does not proceed to logging the user in. If I try to start a meeting, I get the error: **SDKERR\_WRONG\_USEAGE** in the callback **apicallresultcb** This worked fine with the same credentials a couple of days ago and now this happens consistently. The only thing that happened in the interim is that I built an installer and installed the system on another computer. This started happening there, but now it also happens on my dev computer. What changed? What am I doing wrong?   Thanks, ---

hi, i think it is the wrong user type you used. we have two user type to choose. api user or login user. 1\>  StartMeeting and JoinMeeting in the zoom\_meeting.js are for login user. 2\> StartMeetingWithOutLogin and JoinMeetingWithoutLogin in the zoom\_meeting.js are for api user.   could you please to check your code? thanks dats ---

Hi! Thanks for your response. My code is based on the Zoom Electron demo. The code there definitely uses the StartMeeting, not the StartMeetingWithOutLogin. I can tell you that it worked great with my API key and secret along with the username and password. However, I think that the SDK initialization is failing before that becomes relevant. The SDK authentication seems to fail with the error I mentioned. you get that before you start the meeting, it happens when I call SDKAuth in this call: zoomauth.SDKAuth(appkey, appsecret). I think that once that fails, everything that happens after is not relevant anymore.   Ilan     ---
