ERROR 770 Battlefront 2

yes, having this same issue since I bought the game on the regular release date.. Contacted them 3x..... two times via chat and one email. I just got off the chat with my phone to do the UO Trace and had to get my computer. The guy kicked me and I can only call this company during 9-11...they wanted me to DL a UO Trace, I already cleared my map, cleared my ports ect everything I was told I was supposed to do..this is an EA issue...I'm getting this and other server codes as well on the XB1. pissed right now..mid game and oh, connection lost..all points and everything lost.no care. EA FIX THIS!!!!!!! BATTLEFRONT 1 was a a sham, people bought BF2 in good hopes...its been a nightmare . apologize for the grammer
