I was trying to get into Iron Banner just now, the matchmaking screen kept showing the animation of the ship returning to orbit a couple of times, then the screen stayed on the ship as if it was about to load the activity and disabled my ability to exit out of the activity. I killed the client with task manager and started it again and tried again to load into a match. The same thing started happening but after a few minutes it came up with the "honeydew" error code. I read the help page for the error but there's nothing posted on the BungieHelp Twitter.
