i did try disabling ipv6 and enable it both in game, router and network setting.
all of the router, game, launcher, steam network setting that i know off has been tried enabled or disabled.
im using steam to launch the game so proton. and i have tried several version, hotfix, stable and even custom proton to no avail.
currently im trying to install wow in my wife laptop and see if its network or my pc thats the problem
with any luck perhaps she interested in playing together..
