It means we're not supposed to wait at the NPC and spam it till it works. It just makes it worst. Do something else till they report back to us.
Which was an update given 36 hours ago. "Try again later" is pretty vague when we're a day and a half later still "trying again later". So when exactly are we supposed to "try again later"? Please do tell.
