Call of Duty: Warzone has been out for months. But the server connection issue is still a headache for many players. To reduce the hassle and help you fix the issue, we’ve gathered some fixes.

But before diving into troubleshooting, it’s recommended you try signing out and signing in again. If you still can’t connect to the server, try these fixes:

  1. Delete temporary files
  2. Update network adapter driver
  3. Release and renew IP address
  4. Change your DNS server
  5. Use a wired connection
  6. Link your Activision and Blizzard accounts

Fix 1: Delete temporary files

As the name suggests, temporary files are the kind of files that store temporary data that is created by Windows itself or the programs that users use. But they take up some hard drive space which makes your computer slow, which can also impact the responsiveness to the connection. So to make your computer run smoother, you’re supposed to delete those files and it won’t cause any problems. Here’s how you can do this:

1) On your keyboard, press the Windows logo key and R at the same time to invoke the Run box.

2) Type %temp% and then press Enter on your keyboard.

3) Delete all the files in the temp folder. (Press Ctrl and A at the same time to select all the files. Then right-click and select Delete.)

4) If a window pops up saying that The action can’t be completed, simply check the box Do this for all current items and click Skip.

5) Now go to your Recycling Bin from your desktop. Right-click on it and select Empty Recycle Bin.

6) Click Yes.

After deleting the temp files, launch your game to check if you can finally get into the game. If the problem persists, proceed to the next fix.


Fix 2: Update network adapter driver

This error message is related to network or server connectivity issues. So your outdated network adapter driver can be the culprit and your access to the server is blocked. To fix it, you’re supposed to update your network adapter driver, especially if you can’t remember when was the last time you updated it.

You can manually update your network adapter driver by going to the manufacturer’s official website to download and install the correct network driver for your system.

Fix 3: Release and renew IP address

When you encounter the connectivity issue, one of the troubleshooting steps you should take is to release and renew the IP address of your computer, which can help refresh the internet connection.

1) Press the Windows logo key to open the Start menu. Type cmd. Right-click Command Prompt from the results and select Run as administrator.

run command prompt as administrator

When the User Account Control prompt appears, simply click Yes.

2) In the Command Prompt window that appears, type the following command and then press Enter.

ipconfig /release

After releasing the IP configuration from the active adapter, you need to flush the DNS cache in case the cache has become corrupted. To do this, simply type the following command and then press Enter.

ipconfig /flushdns

Once done, you should be able to receive a message that the task has completed successfully.

The final step you need to take is to renew the IP configuration for the active adapters installed in the system. To do this, simply type the following command and then press Enter.

ipconfig /renew

Once done, close the Command Prompt. And you can try to launch your game. You probably would receive an error code on the loading screen. In this case, you can simply click to quit to the desktop. Then you can try again and click on the Play button from the Call of Duty: Warzon gaming title in your library and you should be able to connect to online services.


Fix 4: Change your DNS server

If releasing and renewing the IP address didn’t help you solve the issue, you can try changing the DNS server. It can be beneficial a lot of the time because the standard DNS your ISP gives you cannot always be within your expectations. So changing DNS servers settings, especially configuring Google Public DNS addresses would help you resolve some connectivity issues.

Here’s how you can do this:

1) In the bottom right corner of your desktop, right-click on the network icon and select Open Network & Internet settings.

2) In the Status tab, scroll down and click Change adapter options.

3) Right-click on your Wi-Fi and select Properties.

5) Select Use the following DNS server addresses:. If there are any IP addresses listed in the Preferred DNS server or Alternate DNS server, write them down for future reference.

Replace those addresses with the IP addresses of the Google DNS servers:

Preferred DNS server: 8.8.8.8
Alternate DNS server: 8.8.4.4

Then click OK to save the changes.

After you’ve applied the changes, launch your game and the server connectivity issue in Call of Duty: Warzone should be fixed.


Fix 5: Use a wired connection

If you’re using Wi-Fi or wireless connection on your PC, it’s time for you to see if a wired connection will improve the situation. To do that, use a LAN cable to connect your device to the router and restart the game to check if it resolves your issue.


Fix 6: Link your Activision and Blizzard accounts

Some players have found that linking their Activision and Blizzard accounts can let them get past the “connecting to online services” screen. 

Here’s how:

1) Go to Activision‘s website and login. Once you’re logged into your account, click PROFILE located on the top-right corner.

2) In the ACCOUNT LINKING section, find your profile and link it with your Battle.net account.

3) Click CONTINUE. And you’ll be taken back to the Blizzard website to complete the account linking process.
