I’m having issues starting a meeting. I hadn’t changed the code or any credentials, but now when I try and start a meeting, I am no longer able to. I get this message instead:  
 ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/4/0/4020dec0540737e7522488a1f28aab413e50495b.png). On the browser console, it says:

ERR\_CERT\_COMMON\_NAME\_INVALID

I am unsure of how to fix this, or how this even broke in the first place.

Hey @ameliashort331,

Thank you for providing more information. It looks like you might be using an older version of the [Web SDK](https://marketplace.zoom.us/docs/sdk/native-sdks/web#zoom-web-sdk) as the Web SDK no longer requires jQuery as a dependency. Please test with our [Sample Web App](https://github.com/zoom/sample-app-web) which is using the latest version (1.9.1).

Let me know if that helps.

Thanks,  
Max
