Since the servers upgrade, I literally cannot play the game: every 2 minutes i get disconnected with caterpillar error if I start a story quest, i get disconnected with newt error if I start a crucible match or I am the only one player in the Tower if I drop on... I have tried everything suggested: got a NAT type 2 on the PS4, checked if another device makes some interference with the wifi signal, uninstalled and reinstalled the game (during the reinstall got the same issue), forward every port suggested on the router, got a static IP connected to the DMZ, checked if my ISP is filtering P2P but nothing serena to work! The @BungieHelp did not respond neither nothing in other discussions. The descriptions of both errors says that is am issue related to test on the game servers, so I'm wondering, how much time did those tests will take to be completed? Today I will try with a different ISP and resetting the PS4, but I'm losing all hope due to Bungie only focusing on publicizing the Vault of Glass to hear our problems...
