Connexion problems since update

Hi everyone,
Ive been playing the game since the beginning, and with the last update, i have this annoying connexion problem when i enter in a multiplayers room (warzone/social/rank)

When i first try to enter in a room, i get the “connexion to the halo servers problem something blabla” message. Then i re-try, and no problem i can go to the room and launch the game.
Then each time i finish a game and want to play another game, i have each time the same connexion problem message and i have to go back to the main menu and then re-enter in the room…

Am i the only one who get this problem since the update ?
Are there any known current problem with halo servers ?

Thx
