Can’t connect to ea servers APEX legends ps4

all of a sudden I cannot connect to ea servers on my ps4, it use to work fine and would be no dramas, but all of a sudden it doesn’t want to work, sometimes Data center doesn’t even load, sometimes it says retrieving matchmaking list, and on the odd occasion I do get in, my username just says ‘player’ and I cannot search for a match or even go firing range, it’s like it’s really really slow connection, it says party member preloading, when it’s just myself. I get my friend to invite me and I do get in but I can’t ready up, well on my screen I can’t and his player level is stuck on level 1 and he gets into the match and I don’t. I’ve tried restartting my modem and the game and my ps4 Multiple times. Even changed my DNS on my ps4 and still does not work. It’s weird, it never use to do this at all, and I played it at my mates all weekend with no worries at all, nothing like this happened. I’ve contacted my ISP To open up the ps4 and apex legends ports but I shouldn’t have to, because it’s been working fine since it first came out. I don’t want to have to initialise my ps4 as ive got a few games on there that I don’t want to re download, and same with just redownloading apex. It worked fine on the weekend but this is has been happening at mine within the last week. Could it have anything to do with a new game I downloaded or something.. nothing’s changed and now it refuses to work. Thanks for help 🙂
