**Description** Zoom Meeting Web SDK - connection fails for webinar when practice session is started - kicks user out of waiting room and gives 3008 timeout error If webinar starts user can join If webinar has not started user can join But the case is specific to practice session, if practice session has been started Zoom kicks out the user. Meeting SDK for WEB version 4.0.0 and version 3.8.1 both have the same issue. Expected behavior user remains in waiting room until webinar has been started. **Browser Console Error** ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/3/c/3cc04f5adab9a0006ab6b4afd76b5fc6338919ad.png) **Which Web Meeting SDK version?** 4.0.0 **Meeting SDK Code Snippets** N/A - the Web Client is unable to join. ---

Hi @codemanas17 Thanks for reaching out to us! Are you able to replicate this issue with our sample app? > **[GitHub - zoom/meetingsdk-web-sample: Zoom Meeting SDK web sample](https://github.com/zoom/meetingsdk-web-sample)** > > Zoom Meeting SDK web sample ---

Hi @elisa.zoom, Yes — we’ve tested this with the Sample App as well and confirmed the same issue. **Test conditions:** 1. Webinar Registration enabled 2. Registered user joins Webinar via Sample Web App (added the `tk` in the join parameter in `meeting.js` — line 78) 3. Webinar ID and registered user’s email used to join **Results:** - **Before host starts webinar:** Registered user can join - **After host starts webinar:** Registered user can join - **When practice session has started:** Registered user cannot join — they receive a `3008 meeting not started` error (same as in our implementation) Let me know if you need more details or further tests. _Note:_ We used the CDN version of the Sample App. ---

Hi @codemanas17 Thanks for sharing more details with me. I was able to run our sample app and reproduce this. behavior. This is expected. Registered users can not join the practice session, and this is by design. They will only be able to join once the practice session is over ---

Hi again @elisa.zoom Thanks for taking a look at this. To clarify, we don’t expect registered users to join during the practice session. Instead, our desired behavior is: - When a practice session is in progress, registered users should be placed in the waiting room—not simply blocked by a timeout or given an “unable to join” error. - They should enter the meeting only **after** the practice session has ended. - Currently, the issue we’re seeing is that as soon as the practice session starts, the meeting “times out,” producing a **3008 “meeting not started”** error. That’s acceptable if it happens—but only _if_ the user is queued in the waiting room, rather than flat-out blocked. What’s interesting is that **joining via the Zoom link (e.g., in browser instead of the app) does place users in the waiting room**, which is exactly the behavior we’d like to replicate via the Web SDK. So, to summarize: - Scenario A (via join link or browser): registered user → waiting room → allowed to join after practice session. - Scenario B (via Web SDK): practice session starts → error 3008 → user blocked entirely. We’d like Scenario B to behave like Scenario A: have users held in the waiting room and only admitted once the practice session ends. Let me know if there’s any more information that would help clarify this behavior or assist development. Thanks! ---

Hi @codemanas17 Thanks for sharing more details with me. I tried to follow the behavior you described, but I wasn’t able to reproduce the error. I’m running our sample app: [GitHub - zoom/meetingsdk-web-sample: Zoom Meeting SDK web sample](https://github.com/zoom/meetingsdk-web-sample) When I join a webinar with a practice session in progress, I see the following: ![Screenshot 2025-08-20 at 6.48.52 AM](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/c/6/c69bbad192dc7382c41d225d12e3c34934bade04.jpeg) I’ll send you a DM, if you could share a video of the steps you’re taking and any additional details, that would help look further into this Thanks Elisa ---

### Bug Report: Web SDK Kicks Users Out During Webinar Practice Session **Environment** - **SDK:** Zoom Meeting SDK for Web - **Versions tested:** 4.0.0 and 3.8.1 (same issue) - **Browser:** [insert browser + version here, e.g., Chrome 127] - **OS:** [insert OS + version] **Issue** - When a **webinar practice session** is started, attendees in the waiting room are **kicked out** with error `3008 (timeout)`. - Behavior differs depending on webinar state: **Expected Behavior** - Users should remain in the waiting room until the host **officially starts** the webinar, even if a practice session is running in the background. **Console Output** ```auto [Insert actual console error log here if possible] ``` (Screenshot: 1270×588, showing 3008 error) **Repro Steps** 1. Schedule a webinar. 2. Enable waiting room. 3. Have an attendee join via Web SDK client. 4. Host starts **practice session**. 5. Attendee is kicked out with error 3008. **Impact** - Prevents smooth pre-webinar setup: attendees cannot wait until host starts the real session. - Creates a poor user experience and confusion. ---
