How to Fix Error CE-33945-4 in PS4

Can’t figure out why you see a CE-33945-4 error code on your PS4?

One of the most annoying problems that you can encounter on your PS4 is network connectivity issues. When this occurs, it can prevent you from accessing Playstation Network services, or you may experience lags and delays while playing. 

This can be frustrating when you play a competitive match of Call of Duty, Tekken, or NBA 2K. 

Now, when your Playstation encounters connectivity issues, it may give out a CE-33945-4 error code. This error on the PS4 indicates a problem with either your home network or Playstation’s servers. 

However, there’s no need to get frustrated since this error code is quite common, and troubleshooting it should only take a couple of minutes. 

To help you out, we’ve decided to list down the best solutions for fixing the CE-33945-4 error code on the PS4. 

Let’s get started!

1. Check Playstation Network Servers. 

Since the CE-33945-4 error code is related to PSN, we recommend checking the status of its servers first before changing anything on your console. This way, you can tell right away if the problem is with PSN or your PS4. 

To do this, simply visit Playstation’s dedicated page, and see if there are reported outages on Playstation Network’s services. 

PSN Status

If PSN is down, the best thing you can do is wait it out since server-related errors are not addressable on your end. 

However, if there’s nothing wrong with PSN’s servers, the issue is likely on your end. 

Proceed to the following method to fix the CE-33945-4 error code on your PS4.

2. Restart Your Playstation. 

While this solution may sound simple, it is a very effective method for fixing most problems on any device. Restarting your system will allow your PS4 to reload all of its resources, which may have encountered a temporary bug or error during use.

  2. Next, press and hold the PS button until the Quick Menu shows up on your screen.

4. Check Your Network Connection. 

A slow network connection could also trigger the CE-33945-4 error code on your PS4. When your Playstation can’t communicate properly with Playstation Network’s servers, it may run into errors, which explains the problem.
