Connection error

 
 
  1. Check that PSN services are available.
  2. If PSN is available, test your internet connection. Go to [Settings] > [Network] > [Test Internet Connection] to confirm you can connect to the Internet.
  3. If you see this error in a Party, this can be due to too many attempts to join. Try again later.
