So my connection to multiplayer and the Internet is great yet in the half hour I've been on I've been weaseled 6 times, caterpillared twice, beetled once, and even quailed. I can't even run to the reef to pick up bounties. What the hell Bungie?!
Here are a couple of help articles for the error codes you listed above. I recommend running a Network Trouble Shoot. Also you should try running a power cycle on your console.
Good luck, Guardian!
