**Description**  
Please refer to my issues in below:  
I’ve encountered an issue on connecting with [Meeting SDK](https://developers.zoom.us/docs/meeting-sdk) web socket, but the host share screen is not displaying for other participants. But when we use the zoom link to access into zoom platform, it will show the shared screen.

Date : 12/12/2024  
Time : somewhere around 9.00 to 9.30pm  
SDK : [Meeting SDK](https://developers.zoom.us/docs/meeting-sdk)

**Browser Console Error**

**Which Web [Meeting SDK](https://developers.zoom.us/docs/meeting-sdk) version?**  
3.8.0

**To Reproduce(If applicable)**  
Steps to reproduce the behavior:  
Unable to reproduce for now

**Device (please complete the following information):**

- Device: [Windows]
- OS: [Windows]
- Browser: [Chrome]\*

**Additional context**  
“zoom\_meeting\_id”: 95052143507  
“zoom\_meeting\_id”: 95325652270

By referring to above context, please find my question below :

1. is the “WebSocket connection to 'ws://localhost:12387/” & "wss://zoomsg13422414696rwg.cloud.zoom.us/wc/api/95052143507?dn2=5bCP5Y-v54i\_\_ype"belongs to zoom ?
2. is zoom using websocket to transmit video data ?
3. if statement 1 is true, why does zoom uses localhost in production environment ?

Hello Zoom Developer,

is there any updates on the above raised issue ?

We paid for Zoom Pro license but no one has ever gave us a service/support, everyone is pushing away from issues ?
