Figured since its a few days in i might as well make a thread in hopes of a miracle. I can not follow my friends into games that are 4v4 at all I always get kicked. If Im party leader maybe just maybe it will let me play but that's been like twice over two days. usually what happens is if i try to play and 4v4 mode its just 0004000004 for hours and hours its because of this that I have not been able to play those modes at all since launch was fine everyday in beta except last day.

I have tried every single thing to fix it i have scrounged these forums and other places and not one fix has worked for me I even reinstalled . I also did not do any bete folder mix ups like others. It confuses me since my friends with moderate nat have no problem but I do.

At this point im pretty convinced im screwed at ever truly getting to play this game because it has to be an Ubisoft side problem.

TLdr Op has tried every suggestion imaginable to fix error 0004000004 but 4v4 modes just will not work not even bots unless I fill the party with friends

UPDATE cant 2v2 either can only do it if I have a friend
UPDATE 2 after reseting my router and flushing the dns I was able to load into a elimination which then quickly gave me the 0006000018 error which then gave me 0004000004 and now im back to square 1 of not being able to play 95% of this entire game.
Update3 seems to have fixed for no apparent reason and am now having less problems then ever afraid to ever turn my game off for fear of the bug returning still hope a patch comes out soon
UPDATE4 game has gone back to giving the 0004000004 error for no reason at all and now the game is useless again
