I know this happend to many pple before me, but now i have it too.
I dont change isp/router, and dont change soft version.
I use war2combat to watch, and war2bnet french version to play.
On both, i have randomly 1024/1030 port closed from "note" message.
It worked always fine since today. any idea ?
PS I didnt change os (still w10 since 1 year)
