Problem join friend match and I can't download the DLC

Hi support, yesterday I’ve bought the Borderlands Handsome Collection for Xbox One. Now I’ve 2 problem… The first is about When I try to enter a friend game the game itself say connection to the host after 30 second there is a problem check your cable and didn’t enter the friend’s game.

The second problem is about the DLC when I go to dlc menu into BL2 the game says to me impossible to find the dlc please try again later.

Anyone can help me? There is a fix for this problem?
