Can't join a existing meeting

I started a meeting using the Zoom Api and now I’m trying to connect into it with the WebSdk using the samples but it wont work. The return for the join is “Joining meeting timeout.
The meeting number is wrong.”. The signature uses the JWT heroku with my JWT credentials.

Error
{method: “join”, status: false, result: null, errorMessage: “The meeting number is wrong.”, errorCode: 1}

Which version?
@zoomus/websdk”: “^1.7.8”

Hey @infra,

Make sure you are using the correct meeting id.

If you are still seeing this issue, please email this and the meeting ID to developersupport@zoom.us.

Thanks,
Tommy
