Hi bro I am facing the same problem to I can't enter into ultimate team it takes several attempts. Even if I get in the connection is very slow and its me out of the games. I can login to ultimate team without any troubles using my mobile hotspot.I did everything they ask me to do like opening sports and changing my DNS and all the troubleshooting methods you have mention nothing works. I am facing this problem since the recent update of PlayStation. If you have any solution kindly forward it to me.
