WS-36862-5 PS4 Error Code

Cannot join the Session.

  1. Log out of the PS4 and log back in, then try again.
  2. Ask the party host to send an invitation to you again.
  3. If these two steps do not fix the problem, go to [Settings] > [Initialization] > [Initialize PS4] > [Quick] and initialize the system.
