**Description**

When the host ends the meeting (client.leave(true)), and the guest attempts to join the room simultaneously, calling `client.join(meetingId, token, userName, passcode)` from ZoomSDK returns an error: Error: {“type”: “JOIN\_MEETING\_FAILED”, “reason”: “meeting ended”, “errorCode”: 4004}.

if guest init too long after host ended the meeting. When call client.join(meetingId, token, userName, passcode) will create new meeting session instead.

I want to know exactly when each scenario occurs. Example:

- \< 500ms after the host ends the Zoom meeting\*\*: Calling `client.join(meetingId, token, userName, passcode)` will throw error `4004`.
- After 500ms: Calling `client.join(meetingId, token, userName, passcode)` will succeed and start a new meeting session.?

Thank you very much for your help!

**Which Web Video SDK version?**

Hey @lmtruong1512

Thanks for your feedback.

There is indeed a scenario where the meeting is ended, which is unrelated to the `client.init` method but rather to the `client.join` method. However, I can’t give you a specific time threshold. The issue usually occurs during the process of a user joining a session when the host ends the session.

The process of joining a session involves two steps:

1. **Retrieve the session ID using the topic** : If there is an in-progress session under the same topic, the existing session is returned; otherwise, a new session is created.
2. **Connect to the media server using the session ID**.

This creates some edge cases. If step 1 is completed but step 2 has not yet finished connecting to the media server, and the host ends the session during this time, it results in a `JOIN_MEETING_FAILED` error.

Thanks  
Vic
