The host’s video stream is just black screen when running the Web Meeting SDK.

The host video camera is activated so it’s a problem rendering the video stream.

The DevTools only shows this error:  
zoom-meeting-1.9.1.min.js:2 GET [https://rwcprod.zoom.us/wc/ping/89422600070?ts=1631792336780&auth=m7GzxJZR0gvENRMvVMlVOLHw8SKXzMCPAn2oY6NbX8Q&rwcToken=P5MSXSbT0\_98rH3aO7Y\_Pz5tXHN4BeYtGpMDRebGbN8&dmz=1](https://rwcprod.zoom.us/wc/ping/89422600070?ts=1631792336780&auth=m7GzxJZR0gvENRMvVMlVOLHw8SKXzMCPAn2oY6NbX8Q&rwcToken=P5MSXSbT0_98rH3aO7Y_Pz5tXHN4BeYtGpMDRebGbN8&dmz=1) net::ERR\_CERT\_COMMON\_NAME\_INVALID

@zoomus/websdk 1.9.1

2. Get black screen instead of host’s video

Hi,

Please update to the latest version of the web SDK (1.9.8) and check to see if the issue still occurs. Also, please check to see that your web page and resources are loading under HTTPS.
