If you were online on your PS5 or PS4 and were randomly booted offline, don’t worry, it’s not you and PSN isn’t down either. Sony is automatically signing players out in order for them to accept new terms & conditions.
If PSN is still down for you, try these workarounds
A number of players initially thought that they were being hacked or PSN went down, only to realize they were signed out for the new T&C. Many have voiced their frustration over the forced sign-outs because they were either mid-match in a multiplayer game or unfortunately lost their progress in a game that required online connectivity. Unfortunately, this isn’t the first time Sony’s done this and probably won’t be the last.
Reports mentioning the above are still coming in at the time of this writing, so it looks like Sony’s staggered the rollout of the new T&C. Those who are still experiencing trouble signing back in should first try to restart their consoles. If that fails, try logging out and logging back into the PS App on your phone, and you’ll automatically be prompted to accept the new T&C. Doing it this way will save you the hassle of being booted, if you haven’t yet been prompted.
