Just started getting the same code myself, seems to activate about a minute after loading into literally anything for me. I looked up the code on help.bungie.net (because that's what it says to do when you get persistent error codes) and there isn't even a mention of it on any page, and certainly not a page of its own. I'd guess this error code just got made due to a new server issue on their end that's affecting large amounts of people. Might be fixed soon, might not. Try restarting your game, PC, router, all that type of stuff, although my guess is it wont help anything. I've been watching the Bungie help Twitter and they've been silent there too. Chances are this'll get fixed before too long, I imagine Bungie wants the second half of this weekend's Trials to play out normally, although it's after office hours right now so it likely wont be fixed within the next 12 hours.
I tried quitting and restarting the game, but that didn't do anything. I asked one of my friends and he said he got centipede but went to a different game when it persisted. I'm assuming at this point there isn't really anything the players can do.
