I tried to authenticate my account for DIM (Destiny Item Manager), and it gave me this "An unexpected error occurred while communicating with your selected authentication provider. If this issue persists, we recommend closing your web browser and opening it again. If the issue continues, please visit the Help page for additional assistance." Trying to authenticate my steam account for Bungie.net gave me the same thing. I had to login via my Twitch account just to post in the forum. I restarted the computer, I've tried 3 different browsers, I've logged out and in, I've tried mobile, and nothing works. It appears to be a bungie issue, as the steam authentication screen appears and I am able to login. It simply doesn't go through? Is this actually a Steam issue? I'm not seeing any posts about this anywhere on the help forums, steam support, or twitter... Is this specific to my account? I can still log in to D2 no issues. This seems to be for external logins via Bungie only. I don't play anything else that requires steam authentication (at least not that I can currently recall), so I'm unable to test if this is Bungie or Steam that way...Am I missing something?
