Hello, same issue here. Since the end of May I've been having constant disconnect error 90002. Before that, I didn't have any issues. I noticed that error occurs if I have opened browser or discord running background. When I turn off all third-party programs, the disconnections practically do not occur. Most often the error appears in the evening (7 pm - 12 am. gmt+2 time), almost every minute and when I am in instance. If I am just standing in cities, talking with npc or players, I don't have disconnections. Before that, I played with running browser and discord, there were no problems with my connection. Internet connection is also OK, my antivirus does not block the game.
