Our application in both side (iOS and Android) live now, and unfortunately the app was unable to join the meeting. in addition, we have the SDK in both side in mobile. it was working totally fine, but for now we can't join

Thanks for the update, @hquaemaxima! The first thing I’d recommended is isolating where the problem is happening. You can do so by using the Zoom Meeting SDK Auth Endpoint sample to generate SDK JWT, then manually entering the token to join the meeting. This will help identify if the problem you are seeing results from how you are generating the token. I’ve shared the Zoom Meeting SDK Auth Endpoint sample app below for you to look over.

That aside, can you please share the following information :

  1. Can you share if you reviewed the SDK JWT troubleshooting steps outlined here.?

  2. Can you clarify the role type of the user joining the meeting from your mobile phone?

  3. Do you happen to know how the meeting setting is configured? Do you have registration enabled?
