I tried multiple and all of them failing, currently 2.15.2 but did try: 2.11.5 2.10.1 Looks like it only happens if there is a Admit needed on the host side. But I’m out of ideas right now… It happens regardles of the browser, but I’m using Chrome Version 116.0.5845.97 @chunsiong.zoom Please help 🙂 ---

If the host prolongs it for 5 sec, audio is broken. I can see this error as well, maybe it can help: ![image](https://us1.discourse-cdn.com/flex016/uploads/zoomdeveloper/original/3X/4/c/4cc35b3615a0da5988b6bff66ef5856d4b886c1b.png) ---

@acaledesma No. What I did is I’m using ^2.9.7 version, and that one is good. Other newer version are not working. ---

Ohh thank you for the info, I might try that version. It’s kinda weird that it works on my local (for the latest version 2.18), but it doesn’t work on our staging environment, we’re using nginx without any CSP policy, so it should have work
