As the title says, every time que pops for a dungeon, i click commence and then the game attempts to load, then BOOM 90002 disconnect within 1 second of the load screen. every single time, i can reconnect go the dungeon and finish it with no problems. Walking in to barracks, BOOM 90002, like clockwork evertime I zone into an instanced area i disconnect. I have tried every bit of copy paste instruction such as port forwarding, allowing exceptions in windows firewall, disabling it ( i have no other antivirus or windows securtiy) my pc is currently under dmz right now. still i get kicked every time i zone into a dungeon or raid.

I have done the internet explorer check lists fix, i have had 2 different modems and 2 different pc's since this has started. No problems with any other game, my nat is open, my firewall is down, my ports are unblocked. WOW runs no problems, RB6 siege, pubg, overwatch, apex legends, and even ffxi no issues any where else,

Not sure what to do, i called my isp gave them the tracert information and they claim it is 100 percent not on their end. My friend down the road plays on ps4, no issues at all.

any help is appreciated, thanks in advance
