The error code CE-33729-4 on a PlayStation 4 usually points to a connection issue between your console and the PlayStation Network (PSN).
Possible Causes:
• PSN Outage: Sometimes the PSN servers might be down for maintenance or due to unforeseen issues.
• Internet Connectivity Problems: Your internet connection might be unstable or experiencing problems.
• Firewall or Router Settings: Your router or firewall settings might be blocking your console from connecting to the PSN.
• Corrupted Data: In some cases, corrupted data on your console might be preventing it from connecting to the PSN.
Troubleshooting Steps:
1. Check PSN Server Status:
- Visit the official PlayStation Network Status page to see if there are any known issues or outages.
2. Check Your Internet Connection:
- Test other devices: Try connecting to the internet with other devices in your home to see if the issue is with your console or your overall internet connection.
- Restart your router: Turn off your router, wait for 30 seconds, and turn it back on.
- Use a wired connection: If possible, try connecting your PS4 to your router using an Ethernet cable for a more stable connection.
3. Check Your Router Settings:
- Open necessary ports: Ensure that the following ports are open on your router: TCP: 80, 443, 3478, 3479, 3480 UDP: 3478, 3479
- Disable DMZ: If you have enabled DMZ on your router, try disabling it temporarily to see if it resolves the issue.
4. Rebuild Database:
- Safe Mode: Turn off your PS4 completely. Then, press and hold the power button until you hear two beeps. This will boot your PS4 into Safe Mode.
- Rebuild Database: Select “Rebuild Database” from the Safe Mode menu. This process might take a while, but it can help fix corrupted data issues.
Additional Tips:
- Update System Software: Make sure your PS4’s system software is up-to-date.
- Initialize PS4: If none of the above steps work, you might need to initialize your PS4 as a last resort. This will erase all data on your console, so back up any important data first.
