Call of Duty Warzone Connection Failed Error Fix

Do you get the “connection failed” error when playing COD Warzone? In this guide, we will explain what this error is “Cod Warzone Connection Failed Error” and the solutions you can do to fix it.

Trying to determine the cause behind the connection error can be difficult, especially when your connection works fine with everything you do.

What does the mean of Connection Failed error on Call Of Duty Warzone?

As the name of the error suggests, the “Connect Failed” error is an indication that your PC, PS

4, or Xbox One, is unable to connect to the Internet and play Call Of Duty Warzone because it cannot connect. This connection error is either due to a problem from the game server end, or from the player’s machine or the internet connection to the home network.

When getting a connection failed error, COD Warzone simply won’t allow you to play the popular Battle Royale mode at all.

Reason of COD Warzone Connection Failed error

The Call Of Duty Warzone connection failure error is mainly due to a server issue, but other times, it comes from the end player as well. These are the known common causes of this error message:

Server down.

Popular online games like Call Of Duty Warzone sometimes experience significant server downtime that can last for a few minutes, hours, or even days. While Activision strives to reduce server outages, this type of problem cannot be completely eliminated due to many things that can go wrong. So the first thing you can do if you encounter any connection errors in COD Warzone is to check whether or not it is due to a server problem.

Unresponsive modem or router.

If the game servers are obvious and there are no known issues, the rest of the reasons should come from your side. The first thing to consider in this case is the state of your network equipment, such as a modem or router.

Routers can become unresponsive if left in operation for a long time. Make sure to restart your router at least once every few days to avoid problems with your network.

Change your DNS

DNS addresses may not seem that important at first glance, but a wrong error can make it impossible to load websites or enter Warzone. It may take some time for you to understand that your site has also gone wrong as users are often confused by the slowness of the internet.

If you have never touched your DNS address, it will use the default address that your ISP automatically configures. Changing it to one of the commercially available DNS addresses such as Google, Proton, or OpenDNS will allow you to troubleshoot initial DNS errors.

Slow internet connection.

If the internet connection at home is slow, your PC, PS4, or Xbox One may not connect to the game servers in time. Slow connection can occur if you have a problem with your broadband line, outages associated with your Internet service provider, or if there are too many devices using the Internet at the same time.

Wifi signal interference.

Ideally, you don’t want to use the wireless connection when playing competitive online games like Call Of Duty Warzone. Wifi is less stable than a wired connection, so if you get the connection failed error on wifi, you should consider using a LAN cable to connect your PC or console to the router.

Try using cellular data

Playing games with mobile data is not ideal. The quality of the connection will vary widely in your residential area, and cellular plans tend to be relatively more expensive than residential Internet offerings. However, you will only need to call your mobile phone connection for a few minutes in this case.

Activate the wireless access point feature on your phone to connect to the console or PC. You can also try USB tethering to share data. If you can access Warzone with mobile data, it will verify that the Internet in your home is the one that is working.

Random game bug.

Sometimes games just crash due to a bug or any new changes to the system caused by updates.

Damaged game files.

If you are sure that there are no known server issues and your internet connection is fine, then your COD Warzone connection error may be caused by a corrupt cache or files. You should consider reinstalling the game if this is the case.

How to fix Call of Duty Warzone Connection Failed error?

There are a number of possible solutions that you can try if you can’t play the COD Warzone Battle Royale Mode due to Connection Failed error.

Reboot your device

Sometimes simply updating your PC or console through a reboot can fix technical problems. Make sure to restart your device before continuing with the rest of the solutions in this guide.

Verify your platform’s server status.

Another important thing to do is see if the Call Of Duty Warzone connection failed error message is due to a server outage.

Visit the official Activision page or you can follow their social media pages for any real-time updates and news. 

Check for updates.

Another simple thing you can do is make sure your device’s game and software are up to date. If you’re playing COD WArzone on PC, that also means looking for drivers for your graphics card.

Power cycle the modem or router.

If you are unable to run COD Warzone or are unable to access online services due to a connection error, try running your modem or router cycle to make sure it is working properly. To do this, simply turn off the router and unplug it from the power outlet for 30 seconds. This should be enough to erase the system and hopefully the errors will be removed.

Run a speed test.

To see if the slow connection issue is the main cause of the COD Warzone connection failure, run a speed test on the device you are using. If you are using a computer, open any web browser and go to to check your download and upload speeds.

If you’re playing Warzone on a console, just go to the console’s network settings and run the speed test from there.

As much as possible, you want to get a download and upload speed of at least 5 Mbps when playing Warzone. Anything slower than that can cause network lag or some other connection problem.

If you are paying for fast internet for your home but the speed test result is very slow, there may be too many devices using the internet at the same time. To check, disconnect all devices except computer or console from router or wifi and see if that fixes the COD Warzone connection failed error.

Use wired connection.

Using Wi-Fi when playing online can be less reliable. Try connecting your PC or console to the router via an Ethernet cable and see if that fixes the problem.
