Two years of this bug and still no fix.
And this bug is still there, that BF6 beta is buged too XDDD
Managed to make bf6 work (tried it also for bf1 and it works). I tried this: Launch the game, while the game is running open the Window's settings "Change Adapter Option" (under Advanced network settings), after opening this you will see two icons, one for the PPOE connection and the other for Ethernet, right click the Ethernet one and disable it, then activate it again. Then connect your pc to the internet again and it should work (for me it works). Note that you will have to do this everytime you start the game.
