All the last I trying to understand this problem, on this week I found a method and working 100% for me and my brother in the same network. How is this? Well first open the game normally, and try to join to the team everyone, and destiny shows the error message... In the same press PS button and exit game And same time open de game , and in the same choose char, and try join to team. In my case I can play every day with my brother with this method, no need open ports and no need NAT just try this. I thankfully if any person try this method and share if work while we wait a fix from bungie. Thanks 1-open normally 2- try to join 3-close in the same time the game 4-open in the same time 5-select char in the same time 6-try to joing I can tell , is possible not workt at the first try be patient and try and other time. Please post your report on this thread :) thanks
