How To Fix CoD WWII Error Code 4220?

The first thing you should do is check if the CoD servers are down. If they are, wait for them to come online. Make sure Xbox live is up and running too.
If this doesn’t help, follow the following procedures:

Restart The Console

Restarting your device can help you get rid of processes that are hogging the usage of the RAM. Even though Error Code 4220 points towards a different type of problem, a lot of users have reported that simply restarting their device has helped them get rid of the problem.

So first restart the device you’re playing CoD on. If you’re on PS4, press the power button on the front to turn it off then turn it back on.

If you’re on Xbox, Press the Xbox Button -> Settings -> Restart Console -> Yes.

While you’re at it, try logging in and out of your account too.

Check The Connection

Wireless connections can create lots of issues so it is recommended for you to be connected through a wire. Wired connections help the system achieve optimal performance.

If you’re on PC and use a firewall, forward the right ports to allow the stable connection. You can also try resetting your MAC address on your Xbox. Follow these steps:

  • Open Settings.
  • Go to All Settings.
  • In the console section, Click on Network and then Advanced Settings.
  • Choose your alternate MAC address then “Clear” it.
  • Restart the console for the change to take place.

Right NAT Type

NAT (Network Address Translation) is a characteristic feature that allows your router to share a single IP (Internet Protocol) address across multiple devices on the network.

On Xbox/Microsoft, it is recommended that the NAT type is Open, whereas on PS4 the NAT type should be Type 1. Make sure the NAT type is set according to the recommendations.

On your PS4, Navigate to Settings -> Network -> Connection Status.

Your NAT type is listed at the bottom. Make sure it is set to Type 1.

On your Xbox, Go to Settings -> All Settings -> Network-> Test NAT type in the far right column. Make sure it is set to Open.

Contact a professional if your NAT types are out of place.
