Error 90000 When playing Duty Finder Missions

I always get Error 90k "Connection with server lost" each time I play a Duty Finder Mission/Quest.
Thanks to this I am nearly unable to prgress with my main quests.
And when I am kicked out of the game due to this I will have Error 2002 "Unable to connect with Lobby" haunt me.
I already have that 2002 error almost as default as well so I really really want these problems fixed..... I dnt wanna pay money for a game with these kinda problems as it is severally interfering with my game play. Please resolve this issue!

P.S. I have already posted on the "Request for information: ISPs and P2P throttling" post as well. Please action this asap
