Just started getting this at 2:15 EST. (GMT-5?)
"There is no server in any of the selected server clusters [robertflesch: Development Cluster, Player.IO Main Cluster] that are eligible to start a new room in (they're all at full capacity or there are no servers in any of the clusters). Either change the selected clusters for your game in the admin panel, try again later or start some more servers for one of your clusters."
Was working correctly before lunch. Came back from lunch and no longer able to connect.
