**Meeting SDK Type and Version**  
Meeting Web SDK 3.1.2

**Description**  
We recently updated Zoom Web SDK from 2.10.0 to 3.1.2. Ever since we are not able to connect to meetings as host with ZAK tokens.

Following scenarios works,

1. Joining as Participant with SDK JWT token
2. Joining as Host with the same email address as the SDK App owner email address.

Following case doesn’t work and it gives the Fail to join the meeting error message,  
1.Joining as **Host** with the **email address** that is **different** than the **SDK App owner email address.**

Our application integration with Zoom Web Meeting SDK was live for last 18 months and we have been upgrading Zoom Web SDK on a regular basis and never had this issue.

**Error?**  
Fail to join the meeting

It used to work in 2.10, but not now though. We tried to downgrade it and it is still not working. As per Zoom’s SDK policy, [minimum SDK version](https://developers.zoom.us/docs/meeting-sdk/minimum-version/) supported from Feb 4, 2024 is 2.12.0. We upgraded the Zoom Web SDK around that time and started seeing issues around the same time.

Below are the scenarions that we have tested,

| Scenario | Status |
| --- | --- |
| Join as Participant | Working |
| Join as Participant with ZAK Token | Working |
| Join as Host with ZAK Token for the account admin | Woking |
| **Join as Host with ZAK Token for external user** | **Not Working** |

The last one is not working

@saravana ,

Is the meeting you’re trying to join hosted by a user within your account or outside your account? Zoom has a policy that prevents joining external meetings unless your Marketplace App is listed in the Marketplace.
