Call of Duty: Modern Warfare Error Codes List (And How to Fix Them)

While Warzone is technically an extension of Call of Duty: Modern Warfare, they both tend to get their own error codes. We're separating them based on the two different game types, starting with Warzone. Read below to see how to solve these common error codes!


  • Goldflake: Sometimes, this error code happens while you are in a match or waiting to join. Unfortunately, there is no solid solution, but many players claim that clearing the device cache can stop this from happening.
  • hk:s = #####m: These error codes are tricky and frustrating. Like the Goldflake error code, there is no official solution. The best option we have found is also clearing your device cache.
  • Error Code 262146: This error shows up during server outages. Unfortunately, there is nothing you can do except give it some time and try to join again when the server is up and running.
  • Error Code 6036: This error code seems to happen exclusively on the PC version of Warzone. Most players that run into this error code have reported that you can resolve this issue by forcing an update on the game or once again clearing your device cache.
  • servers are under heavy load. You have been entered into the queue and will be joined to the game shortly. Generally, this error code resolves itself. It happens frequently for PC players, and it simply means too many players are trying to join at the same time. It places you in a queue to let each player in slowly instead of all at once.
  • Unable to access online services. This error code for Warzone can be the most frustrating, as there are a number of issues that could be going wrong. The most frequent cause of this error is that the device you want to use is not connected to the internet. To fix this issue, you simply need to make sure your device is connected. If it is, make sure no other devices in your home are taking up too much of the data traffic.

Modern Warfare

  • Error Code 656448: This is generally an issue on the server side. Unfortunately, there is not a lot of information available on this error code, and as such, there is no solution but to try again. There is some speculation that restarting your device can help, but this is likely just because of the time it takes to reboot.
  • Error Code 4: This error code seems to be exclusive to the PC and is likely caused by old information in the installation folder. To solve this, go to the Documents folder on your PC and find and delete the Call of Duty Modern Warfare folder.
  • Error Code 2048: Sadly, this error code doesn't have a solution. It is believed to be an issue caused by trying to connect to the servers with an older version of the game. The first thing to try is to reboot your PC, as this has worked for some people, but it's rarely a solution. If all else fails (and your certain the server is up), a full re-install might be necessary.
  • Error Code 65538: This is generally an issue caused by selecting the wrong region to play the game. To solve this, go to Region, select Options in the Menu, and change it to the region that matches your location.

This list can change often, and we'll be adding new error codes and solutions as they come in. If you know of any other error codes and are looking for a solution, drop us a comment! Pro Game Guides is here for you.
