Due to increasing demand to view the live video stream I've added another server - from my personal stash - to the array you can choose from upon entering the project. This server is also located in the US, in Texas.
Some people have reported better chances when choosing different servers, even ones which seem further away. Loads of reasons this could be... but there are loads of sites that can explain that better.
One of the issues has been only one server - the US/AP one - was capable of serving a stream that could get past certain firewalls. I've reconfigured the other servers to allow this now so you may find you get a better response from a server that wasn't working yesterday.
