I have been playing destiny a lot since launch without any problems. Yesterday I began receiving the errors flatworm and beaver after making no changes to my network. The errors a first were stopping me from transitioning between zones but then got worse and I couldn't even make it to the tower. I tried most if not all the troubleshooting methods available too. First port forwarding, those Bungie specifies and the ones Sony recommends for the PS4. I have always had a wired connection directly to the modem so no change there. (I have a hybrid modem router device) I lowered and eventually disabled my firewall. I finally gave the PS4 a static IP and put it in my DMZ. None of these fixed the problem and since I wasn't having issues until now I can't help but think this is a Destiny server issue.
