The WebRTC signalling can take a long time (I've seen up to 2 minutes) because your browser has to find a way that other browsers can tunnel in to your network.

The WebRTC signalling can take a long time (I've seen up to 2 minutes) because your browser has to find a way that other browsers can tunnel in to your network. Once you're connected messages seem to go through fairly quickly. The fastcast.nz error is because that signalling server is down and has been for a while but you can safely ignore it. The "ICE failed" error might be because you are behind a very restrictive firewall. Thanks for trying it out!
