I was just coming here to ask the same thing! First, my game crashed. When I reloaded, I got the error message for the SDX. Hit the try again button, but same result. Thought maybe the crash had messed up my internet, so I rebooted my console (Ps5). Now the main screen looks like I’m not online, no gallery exist, and the game keeps trying to download something from the SDX and erroring out. It all looks like Sims 4 has no connection to the internet, but I’ve verified other games connect just fine.
