Nice - good luck with the Hackathon!
I'd be 99% sure the issue is to do with a lack of HTTPS as @Robin says. The other one to watch out for is that you can only connect to a device in response to a user input (not when a page starts) but it looks like you're doing that anyway.
If you can't get HTTPS out of elastic beanstalk for whatever reason but still want to use that URL (maybe to access other AWS stuff?), you may be able to use a simple HTTPS page from GitHub inside an iframe, and then
window.postMessageto communicate between the two pages - it's a bit of a hack, but it should work.
