G15 errors: Over the past few weeks, we've added loads of logging, pored over code submissions, and continue to search for the source of our G15 issues. A G15 is the error you see when you can't connect through your "gateway" to the server. This is not something that's wrong with your computer or connection. The only "fix" is to wait for a while and try again later. However, we do have a bandaid in place that should cut down on G15 issues substantially, by shutting down broken gateways after enough connections get stuck on it.
