This was a problem with our CDN, especially in Asia. To be specific, your client was being told to grab image assets from our California servers not the Asian servers, and the resulting latency was causing the client to fail. It probably shouldn't fail like that, which is something we'll probably want to look into at some point, but one workaround is having a global CDN like we have, so we have to get that fixed, first. Sorry to any players from Asia who were unable to play during this play test. We'll be doing another weekend test soon and we expect the issue should be resolved by then.
In the future, by the way, if you need immediate help it's best to ask in the Help channel. During playtests we spend most of our resources watching and working with the live game, and we typically go over forums posts at the end of play sessions, so it's very likely if you ask a question here that needs immediate attention, like if you're stuck someplace, you may not get a response until it's far too late. Sorry about that, soapbubble.
