Call Of Duty Modern Warfare 2 Hueneme Error [FIXED]

Here we go again, another day, another error in Call of Duty Modern Warfare 2. We have already covered some major Crashing Bugs in Call of Duty MW2. Now for the first time, we are set to cover the first connection error in the game. Many people have reported that they are facing the Hueneme Concord Error. Hence, to help the masses, we have searched and compiled the top fixes for Call of Duty Modern Warfare 2 Hueneme Error.

With that said, let us not waste any more time. Here’s a quick overview of the Hueneme Error, along with its solutions for MW2.

How To Fix Hueneme Concord Error In MW2?

The MW2 Hueneme Concord Error affects PC, PS4/PS5, and Xbox players. It’s related to connectivity and server issues, not your device. Here are technical fixes that may help resolve it, but be patient and try them all, as effectiveness can vary.

Connect To A Different Internet Connection

The easiest fix for the Hueneme Concord issue in Call of Duty has been a simple change of internet connection. Since the problem is caused by server connections, sometimes your own Internet can be the one at fault. To check whether your internet is causing the problem, you will need to connect with a different internet connection.

An easy way to do this is by turning on Cellular Data on your Mobile Phone. Follow that up by turning on your Hotspot sharing and then connecting your relevant platform to your phone’s 4G/5G connection. After your PC, PS, or Xbox has successfully connected with your phone’s hotspot, try running Call of Duty Modern Warfare 2.

If you don’t see the Hueneme Error anymore, that means your Internet is at fault, and you need to contact your ISP to change your NAT Type. However, before you do that, we recommend you try out the rest of the fixes mentioned below.

Set Up Port Forwarding

By port forwarding your Internet, you will allow it to access private data that may be restricted by a firewall otherwise. These restrictions can cause network and connectivity issues on your system and make it harder for Call of Duty MW2 to connect to a server. If that is the reason why your game hasn’t been connecting to the server, then you can try port forwarding on your PC.

Unfortunately, port forwarding is a tedious process and can be difficult to do for people who aren’t really accustomed to internet and router settings. Hence, we would advise you to first reach out to your ISP or anyone who knows how to set up port forwarding.

The Port Forwarding process can vary from router to router, therefore, there isn’t a fixed method to perform it. With that said, let us now go through all the general steps you need to perform in order to set up Port Forwarding for Call of Duty MW2.

1. First up, you will need to acquire a Static IP Address.
2. After you have access to a Static IP Address, go to your Router Settings.
3. You can access the router settings through your browser by putting in your assigned IP Address (you will also need the username and password assigned by the ISP).
4. From the Router’s Admin page, locate the ‘Port Forwarding‘ option from the given categories.
5. Now edit the TCP or UDP in the Port Forwarding settings within your Router Settings page (we have included the port addresses down below, which you can refer to).
6. Apply the Settings and close the browser.

If you’re still confused about what TCP and UDP then here’s a quick list that covers all the various platforms. Use the ports which are mentioned next to your platform (PC, PS, or Xbox).

First up, players who are playing on PC must use the following ports:

• TCP: 3074, 27015, 27036
• UDP: 3074, 27015, 27031-27036

Players who are playing on PlayStation must use the following ports:

• TCP: 3478-3480
• UDP: 3074, 3478-3479

Lastly, players who are playing on Xbox must use the following ports:

• TCP: 3074
• UDP: 88, 500, 3074, 3544, 4500

If that doesn’t do the trick for you, then continue and try out the next method on our list.

Use A VPN

Activating a VPN has worked for the majority of the player. However, it is only a temporary fix. Since playing on a different server can be a hassle. Despite being an underwhelming method, it still does the job and has been by far the most successful fix so far for the issue. Hopefully, Call of Duty Modern Warfare 2 will patch the error soon enough. If you certainly can’t wait until then, you should consider connecting to a VPN.

Connecting to a VPN is pretty straightforward. Although, it goes without saying that low-tier VPNs do not work well with video games. Hence, if you’re planning to utilize the method, then you should have access to software such as NordVPN or ExpressVPN. Load up the relevant VPN provider and select a location near your present location. 

The reason behind this is to keep the latency at a minimum. If you choose a location far away from your actual location, then you will end up facing high latency in-game. With a good VPN running at the back, you will avoid connectivity errors in Call of Duty MW2. Hence, if everything else doesn’t work, then shift your focus toward a VPN.

Clear Cache

Clearing the cache on their system is another technique that many users have tested and utilized to fix the Hueneme connection error in MW2. Sometimes the cache on your system may clash with the game, which can cause connection issues. Hence, to quickly fix the problem, you can clear up the cache on your system from time to time. 

Doing so will ultimately fix issues, such as the Hueneme Concord error in Call of Duty Modern Warfare 2. Luckily, there are swift methods to clear the cache on PC, PS, and Xbox. In this section, we will run you through the steps of clearing the cache on each of these systems so that you can get back to the Modern Warfare 2 Multiplayer mode.

Check Your Region In Activision

For some people, the Region on their Activision account was changed to another country. Which ultimately caused the connectivity issues in Call of Duty Modern Warfare 2 servers. However, changing back to their original region instantly fixed the Hueneme Error. That is why we decided to include this fix in our guide since a few people on the internet seemed to benefit from it. 

To check and change, your region on the Activision account is pretty simple. All you need to do is open up the Activision site and Log In to your account, which is linked to your platform. Once you log in, press the ‘Profile‘ option found on the top right of your window.

After the profile page loads up, you will notice a Tiny Flag on the top right corner of your screen (on PC). Simply click on the flag and change your region to the one you were using. If your region was changed, then there’s a high chance that it was causing the Hueneme Error in MW2 for you.

Just to be sure, also check the physical Address of your account. Your address can be found on the ‘Basic Info‘ tab in the Profile menu.

With that, we reach the end of our guide. We hope that after reading through our article, you found a fix for the Hueneme Concord Error in Call of Duty Modern Warfare 2. We dug deep into the depths of the internet to find methods that have proven rewarding for many players.
