cannot enter a match with my party

after a match it gets stuck on the game summary. (when it tell you the best squad, how well your squad was, etc) it says [continue in 0] and nothing happens.
but if I go to the menu, being in a party starts entering the next map. except that sometimes it doesnt enter the map, even tho my friends tellme that there are bots it the match it does not enter.
I go out of the party and enter the same party and the same happens . sometimes the Queue appears but it does not enter (knowing that there are bots in the match cause my friends told me), sometimes the queue appears then dissapears after a bit, sometimes 3 minutes, sometimes 1 .
but the thing is that I cannot enter until it loads the next map. 
when im in lobby and cannot enter the match with my party I try to enter by clicking "join game" on my party friends and it gives me this error: 870039:620015:-8A

this happens every 3 matchs played approximately
