I fixed my hare/rabbit/centipede/cattle/caterpillar errors that rendered the game literally unplayable by removing the double NAT in my home network - put my modem into bridge mode. You might have a double NAT if you have a modem and a separate router/wireless gateway combo. The modem does one NAT and then the router performs a second NAT. Even if you forward ports, enable UPNP or configure DMZ mode on both (I had) it could still prevent everything from working. Also, if you have an Xbox one then run the multiplayer network diagnostic under the settings menu - it helps to ID where the problem lies very well. If you post it with your bungie error code it will make things easier for all.
