My audio and video are malfunctioning

Your internet speed probably is the reason for the malfunctioning of your audio and video. Go to the test page to check your internet speed. If the test indicates that your internet speed is too low you might be able to switch to another internet connection. Refreshing your browser with F5 can possibly solve the problem.

My video stream is shutting down

You can refresh your video stream with F5. This solves the problem in most cases.

There is an echo in my audio stream

The webinar is probably playing simultaneously in two or more browsers. Please close all expandable browsers and continue watching in just one browser.
