Hi all

- I am currently doing a developement using Zoom Web SDK with Zoom sample web app, like this:

```auto
ZoomMtg.init({
    ...
    success: function(res){
        ZoomMtg.join({...})
    },
    error: function(res){...},
});

```

- Since I am doing development, I need to refresh the page a few times

- Which means, the Zoom `meetingNumber` is different each time after refresh

- Here is the scenario: When the page first load, I can create, init and join a meeting as host,

- When I refresh again, I got an error 3008 `Please join meeting first!`, which is normal as I am being seen as doing concurrent meeting

- Now here is my question:

Thank you very much in advance

Hey @alucard001,

Thank you for reaching out to the Zoom Developer Forum. First, make sure that when you are attempting to join the meeting you change the role you’re using to `1` and regenerate your signature.

If you would like to leave a meeting when you refresh the page, the best option is to add an event listener to the `unload` or `beforeUnload` events. Within your event listener, you can try calling the `ZoomMtg.leaveMeeting()` function.

I hope that helps! Let me know if you have any questions.

Thanks,  
Max

Hi Max. Yes I am using role 1 when refresh. And since I am using role 1, I got a new meeting id with new sig, and it kept showing the error that I cannot join a new meeting.

Regard to the unload event, I’ll try that and see how it works.

Thank you.

Hi Max

The problem is fixed now. Thank you. I use `beforeunload` to do `leaveMeeting()`.
