500: Internal Server Error Something bad has happened. It’s not you. It’s us. We all make mistakes, and this one was totally ours. Click the back button to go back where you came from. We don’t want you to see us like this. Anyone else getting this while trying to link their steam account?
Bungie is aware, it appears to be affecting most, if not all players. As a test I tried it myself and received the 500 internal server error. XBox, PSN and Battle.net all authenticated fine, but Steam appears to not be working correctly.
