Bungie has already shut down the servers hours ago, there are problems that could be fixed so far only conditionally. There are rumors that the problems with the Google Stadia release have to do, but this has not yet been confirmed.
Bungie Help @BungieHelp We are continuing to investigate issues preventing Destiny 1 and Destiny 2 players from signing in.
Currently, Destiny 2 is DOWN, and players cannot log in to the game from the title screen from PC, PlayStation 4, Xbox One or Stadia. Bungie says he is working on the subject, but it seems that both Destiny and Destiny 2 have been inactive for at least a couple of hours.
The game Destiny 2 Update is available now for PS4, Xbox One, and PC.
