What is the Detrick Guernsey error? – CoD MW II Beta Failed Connection 

Call of Duty Modern Warfare II Beta is in its initial release stage for now. The release was a two-part event with the game being made available to PlayStation users during the first week, i.e., 16^th September to 20^th September 2022. Subsequently, the beta version was rolled out for gamers of other platforms like PC and Xbox during the second week, from 22^nd September to 26^th September 2022. 

Gamers seem extremely pumped to experience a glimpse of the whole game. However, to their disappointment, an error occurs when they attempt to log in to the game.  

The Detrick Guernsey error in Call of Duty Modern Warfare II Beta is a login error experienced by gamers while trying to sign in to the game. Moreover, this issue appears after players accept the licensing agreement and adjust brightness. Unfortunately, it prevents gamers from successfully initializing and playing the game. 

Here’s more about the Detrick Guernsey error in CoD MW II Beta, including why it occurs and how you can overcome it. 

Why does the Detrick Guernsey error occur in Call of Duty Modern Warfare II Beta? 

The Detrick Guernsey error in Call of Duty Modern Warfare II Beta occurs due to the servers being down. Such an error arises when the servers aren’t online, as the developers are still working on them. This seems reasonable as the game is still in its Beta stage and might require maintenance to achieve an error-free full version. 

Moreover, the error is known as the Detrick Guernsey error, as that’s the error code displayed by the game when players try to log in. The exact error warning is as follows. 

“Connection Failed – Login Servers are currently undergoing maintenance.” 

Reason: Detrick Guernsey

It’s noteworthy that a “logging into Demonware” message precedes the error. Nevertheless, it doesn’t lead anywhere, resulting in a failed connection. 

How to solve the Detrick Guernsey error in Call of Duty Modern Warfare II Beta? 

As the Detrick Guernsey error was discovered in the first week of the Beta program, the PlayStation gamers were the first to experience it.  

Shortly after, rumors suggested that developers had found a solution and that they would fix the error by the second week of the Beta program. However, this rumor was mere speculation, and the Detrick Guernsey error persisted. 

Since the whole fiasco, Activision has supposedly supported reports saying there’s no problem to be fixed from their end, and the issue might be user-specific.  

If that’s true, here is a list of tips and tricks for you to fix the Detrick Guernsey error in Call of Duty Modern Warfare II Beta.  

• Method 1 – Change Network Connection  
• Method 2 – Use VPN Software 
• Method 3 –  Log in with Another Account 
• Method 4 –  Scan and Repair Game Files 
• Method 5 –  Delete Document Folder 

Method #1 – Change Network Connection 

You can try to fix this error by changing the network connection of your gaming platform.  

If you’re playing on a Wi-Fi connection, try switching to an optical fiber connection or resort to your mobile data. Similarly, try shifting to a Wi-Fi connection if you’re already gaming on your mobile data or optical fiber. This approach resolved the error for a few Call of Duty MW II fanatics. 

Method #2 – Use VPN Software 

You might sometimes face the Detrick Guernsey error if the servers for your country or location are down.  

You can overcome this obstacle by downloading and installing VPN software. This method will allow your platform to hide its IP address and take over the IP address of a location where the servers are still up and running. 

Method #3 – Login with Another Account 

When the underlying issue isn’t thoroughly known, you can attribute matters like the Detrick Guernsey error to be account-specific. As a result, you can try fixing this error by logging in via a different account. This won’t be difficult if you belong to a circle of passionate gamers or Call of Duty admirers.  

Method #4 – Scan and Repair Game Files 

A few connection problems in the game can stem from faulty or corrupted files. Follow the below steps to repair these files and tackle the Detrick Guernsey error. 

1. Open the game launcher consisting of Call of Duty Modern Warfare II. 
2. Log-in to your account 
3. Look for the Settings icon in the form of a tiny gear and click on it. 
4. Search and click on the Scan and Repair tab 
5. Wait for your game to be automatically repaired 

If your system still faces the Detrick Guernsey error, the next method is your only hope. 

Method #5 – Delete Documents Folder 

If you’re a PC gamer, go to the Documents folder and look for the Call of Duty Modern Warfare II game file or save game. Then, delete the folder, as it contains your account’s credentials.  

This workaround might work as sometimes a user’s account becomes prone to glitches and may require a deep cleanse to function correctly. 

Notably, this method of eliminating the Detrick Guernsey error leads to the deletion of all your progress. However, one could argue that it’s better to play a game and start over rather than not be able to play it at all.
