Mass Effect 3 Multiplayer Online Pass Required Error
To summarize, this all began when I tried to play Mass Effect 3 on PC with some friends for the first time in a couple years. I installed the EA app (since the Origin client recommended it) and then installed Mass Effect 3 on my computer. After it installed, I launched the game and tried to enter the online multiplayer, but instead of it working, I got the "An online pass is required to access online features of the game" error. After some searching, I found this was a common account entitlement error on EA's end.
