I'm encountering an issue that started up sometime last week (3-4 days ago?) where the game abruptly brings up a black screen in the middle of playing (music and mouse cursor still active). In addition, whenever I enter character selection screen, when I select a character it will result in 0 ping and after a while will close the game back out to the log-in prompt. I am wondering if anyone else is encountering this issue recently.
As for what I have done to try to resolve the problem, I have clean installed the game again, redid & rechecked my router configuration, re-installed my graphic drivers, rolled back windows 10 update. My internet connection & graphic performance is fine for all of my other games, it is just GW2 giving me the problem.
