"Couldn't load resource" — a failed asset download. Clear your cache and reconnect.
"Connection timed out" — either the server is restarting or your network dropped. Check the status page.
"You are not whitelisted" — exactly what it says. Check your dashboard for your application status.
"Server is full" — join the queue and stay in it. Priority queue is available in the store, and yes, that is the honest answer.
