The site gets back, after a successful oauth process, the parameters: error=server_error error_description=You lack the privileges to read or write this data. state=<censored> This reproduces for me, and at least some others, on https://light.gg/ and also http://destinyitemmanager.com It looks like the issue is on the bungie API side, somewhere. Clearing data (cookies, etc, using the "delete everything" option in Chrome) on all of battle.net, bungie.net, and the relevant sites, doesn't change the outcome. Current Chrome on Windows. Happens only on reauth, I had to log out and try to log in again on DIM (Destiny Item Manager) to see the issue, before that it was perfectly able to read data on the old authentication. Also maybe interesting from the requests: x-bungienext-mid2: 20 x-bungienext-renderer: Frog Blast the Ventcore I can get additional headers, etc, if you desire, just LMK what.
