How to Fix It “Unable to Access Online Services” on Warzone

Before moving on to the solutions to the problem, it is best to understand that you get the error when the server is out. You may also get the issue if your computer has a hard time connecting to the internet or the server.

Now that we know the cause let’s look at the solutions below.

Check Server Status

Before changing settings on your system, you can check if the Warzone servers are online or not. You can go to Activision’s support website and check if the servers are running.

Once you are on the support page, browse the drop-down menu on the right and select Call of Duty Warzone. You can then see if the servers are online on all platforms.

If the servers are offline, you will have to wait until they are back on. But if they are running and you still face the error, you can move on to the next process.

Restart Devices

Preliminary fixes include all the easy and small steps that you can do to remove the possibility of minor bugs. You can restart your PC, game, and router to eliminate the bugs or glitches that might appear during startup.

Close Background Apps

Additionally, you can also close the background apps that can hog up your internet connectivity, such as Google Chrome or other internet browsers. You can head over to the Task Manager and kill the processes so that they do not run in the background.

Switch To LAN

If you are connected over WiFi, switching to a LAN connection is advisable if possible. Wired connections give you more stable internet connectivity than WiFi. However, if switching to LAN is not possible, try to move as close as you can to the router. You can also try disconnecting other devices on the same network so that you do not share bandwidth with them.
