Could not connect to the server within the time limit. Connection may be busy or temporarily unstable.

Step1: Go to [Settings] > [Network] > [Test Internet Connection] and check the network status. Retry connecting to the network.

Step2: If the error persists, the network may be unstable. Try following:
- Restart the system and retry.
- If you are using a Wi-Fi connection, place the PlayStation 4 system and the router closer together, make sure there are no obstructions between them.
- Other devices on your network might be using a large amount of bandwidth. Wait until they are finished.
- Try other to connect to a different network if available
