**Meeting SDK Type and Version** I am using server to server oauth with Zoom WebSDK 2.11.0 Even I upgrade to 2.18.2, I still get the same error Actually, in my code, I found that my SDK key is “I6vYgc19Rv6b7q8ypI\_2Ow”, but I cannot find it in my app (in marketplace) (why is it disappeared? removed by zoom?). But I can still find the server to server oauth app with another client ID. I tried to replace them, but it is still not working. **Description** Today, when accessing the zoom meeting/webinar, the browser prompts error: Joining meeting timeout. Signature is invalid. The same program code is working fine last week. **Error?** here is the console log: Object { sdkKey: “hL2m0bL1T02s\_loJQbgBJg”, meetingNumber: “89077581472”, userName: “R-681521”, passWord: “205709”, leaveUrl: “/zoomleave.php”, role: 0, userEmail: “[R-681521@hidden.mpplication.com](mailto:R-681521@hidden.mpplication.com)”, lang: “en-US”, signature: “eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzZGtLZXkiOiJJNnZZZ2MxOVJ2NmI3cTh5cElfMk93IiwibW4iOiI4OTA3NzU4MTQ3MiIsInJvbGUiOjAsImlhdCI6MTcwNDcwNjcxOSwiZXhwIjoxNzA0NzEzOTE5LCJ0b2tlbkV4cCI6MTcwNDcxMzkxOX0.GEbWKuDCR-a3aiF0AC7twaXCqnMx6R8LteTzGFBxlAU”, china: false } [meeting.js:66:17](https://demovideo.mpplication.net/vendor/zoom/CDN/js/meeting.js) signature eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzZGtLZXkiOiJJNnZZZ2MxOVJ2NmI3cTh5cElfMk93IiwibW4iOiI4OTA3NzU4MTQ3MiIsInJvbGUiOjAsImlhdCI6MTcwNDcwNjcxOSwiZXhwIjoxNzA0NzEzOTE5LCJ0b2tlbkV4cCI6MTcwNDcxMzkxOX0.GEbWKuDCR-a3aiF0AC7twaXCqnMx6R8LteTzGFBxlAU [meeting.js:67:17](https://demovideo.mpplication.net/vendor/zoom/CDN/js/meeting.js) Uncaught (in promise) DOMException: The play method is not allowed by the user agent or the platform in the current context, possibly because the user denied permission. pre load wasm success: [https://source.zoom.us/2.18.2/lib/av/audio.encode.wasm](https://source.zoom.us/2.18.2/lib/av/audio.encode.wasm) [zoom-meeting-2.18.2.min.js:2:4194053](https://source.zoom.us/zoom-meeting-2.18.2.min.js) pre load wasm success: [https://source.zoom.us/2.18.2/lib/av/video.simd.wasm](https://source.zoom.us/2.18.2/lib/av/video.simd.wasm) [zoom-meeting-2.18.2.min.js:2:4194053](https://source.zoom.us/zoom-meeting-2.18.2.min.js) inMeetingServiceListener onMeetingStatus Object { meetingStatus: 1 } [meeting.js:111:15](https://demovideo.mpplication.net/vendor/zoom/CDN/js/meeting.js) An AudioContext was prevented from starting automatically.
