I am able to join a meeting using the Web SDK (ZoomMtg.join). But when i try to join with a webinar meeting id, it fails. It says Joining webinar timeout.
Error
Joining webinar timeout.
Your connection has timed out and you cannot join the webinar. Verify your network connectivity and try again.
I had the same issue, as Tommy says set the email address, and also to ensure that the email address is NOT the email address of the HOST. i.e., it must be a different email address.
