How fix this error? I did change DNS, but this didn't help Was facing the same issue - "Failed to download configuration files from Bungie servers error code: nightingale" What did the trick for me is to change DNS to google (8.8.8.8 and 8.8.4.4), got the solution from this thread https://www.bungie.net/en/Forums/Post/236965675?sort=0&page=0&path=1 I've also disabled IPv6 Played a game for about an hour, tied re-launching it a couple of times - work fine for now
