Cameras and microphones turning off every few seconds is normally caused by a browser issue or a network firewall. We first recommend updating your browser. After the update is complete, it maybe necessary to restart your computer or relaunch the browser (click quit, then re-open). Sometimes Chrome's automatic updates may not finish without restarting your computer or relaunching the browser.* This has been known to cause camera and mic issues within a webinar. Completing the update, and relaunching the browser should fix the issue.
However, if you are seeing an UNABLE TO ESTABLISH CONNECTION screen, you are most likely behind a firewall. If happens, you may need to contact your IT person. The linked article explains in more detail what you can do to circumvent (if possible) your network's firewall.

*When possible, turn off your computer when you are not using it. Restarting your computer on a normal basis is necessary for software updates on your computer. Make sure you are always using the most up-to-date browser and operating system, whether you are using a MAC or WINDOWS device.
