When I started to play I had no error codes like bee and canary. Not long ago we got a new modem, the error codes were popping up so much that it took me 10 tries or more to get in the tower or reef. PVP was a no-go. I looked up some solutions that other people considered, using portmapping. That didn't worked or I made some mistakes. After that I was checking other settings of my modem, then I found the solution of the error codes I had. The solution for my error code was making a static IP for my PS4 with the DHCP of my modem and enabling DMZ host of that IP in the firewall settings of the static IP. I don't really understand what DMZ is :P but I hope I can help some people with this information. Sorry for my bad English.
