WebSDK - Joining Webinar timeout


Hello. Since April 13 I’ve started encountering the issue for each of scheduled webinars. This occurs every time I’m trying to join a webinar with a paid zoom account user as the host.The previous solutions doesn’t work too: sdk version is the latest one, and there is no userEmail collision because of only one user is joining at the moment.

WebSDK 1.9.1

Joining webinar timeout.

Thank you for providing that screenshot. Are you able to also provide a screenshot of the browser console when this error is shown ?

As I wrote there is nothing special, it’s the same output as for a successful join.

I guess, the only way to handle this error is to hook it in the client?
