Only some users (who don't store their media permissions in their browsers) seem to be affected. I can trigger it with Firefox in incognito mode. The browser console reports some errors, please see the attached screenshot.

For now, I can say that having a browser, that has never seen the BBB instance before, is not a sufficient condition to trigger the problem. I had a counseling interview with a student yesterday who never has had contact with our BBB 3.0.0-alpha6 server, before. He was able to join without any problems.

The phenomenon is currently occurring randomly here. After a server restart, users can participate who were not able to before and vice versa.
Is there an update on the bug? Or is there a planned time frame for fixing it? :)

Hello!

There is a chance that this error is related with the recently implemented server-side cache of meteor bundle.

If you hit this error again, please login into server and run this command:

sudo rm /tmp/meteor-assets-nginx-cache/* -rf

Let us know if it helps.

PS: this cache will be generated again, so it's just for confirming that this solves the problem, if so, we will investigate a better fix.

If you hit this error again, please login into server and run this command:

sudo rm /tmp/meteor-assets-nginx-cache/* -rf

It's important to reload the browser tab with this option enabled in "Developer tools":
