Unknown error code

I'm getting the exact same unknown error now when trying to connect to a multi-player game.  This games been nothing but frustrating.  Game disconnects when it goes to load the next map, random screen freezes and I have to close BF1 down with Windows Task Manager then re-launch it.  It goes on and on.  I want to like this game but it is riddled with bugs.  I'm not expecting a solution even though I paid $120 for this game.
