Do you see a ‘lost connection to game server’ error on Overwatch 2?

It can be annoying when Overwatch 2 starts normally then shows an error that says ‘lost connection to game server’ and closes after a few seconds. 

This leaves you staring at your desktop without any clue of what went wrong. 

There are various reasons for this error message on Overwatch. Trying to fix this issue by troubleshooting should not take longer than 30 minutes. 

In this article, we are going to walk you through the process of how to address this error on Overwatch 2. 

Let’s get right into it!

1. Check Game Servers. 

If Overwatch 2 doesn’t even make it to the main menu, it usually indicates a problem with the game servers. 

Due to this, we suggest checking Blizzard’s servers using third-party sites like Downdetector

If there are reported problems with the game within the last 24 hours, it is likely that the servers are down. 

Sadly, server-related issues can only be resolved on Blizzard’s end. Check in from time to time so you’ll know once the game is up and running. 

On the other hand, you can proceed to the next step if there’s nothing wrong with the servers. 

2. Restart Your Computer. 

Before changing your system configurations, try restarting your computer first. 

While this might look very basic, restarting your device does a lot of things. For one, it flushes your memory so that it’s free from corrupted data. 

Restarting your computer also reloads crucial resources that could be causing network problems and errors. 

Here’s how you can restart your PC: 

  1. Click on the Windows icon in the Taskbar
  2. Now, access the Power Options tab. 
  3. Choose Restart from the pop-up menu. 
Restart PC

After restarting your computer, relaunch Overwatch 2 and check if the error message would still occur. 

3. Check Your Network Connection. 

A problem with your network could also trigger the ‘lost connection to game server’ error on Overwatch 2. 

To confirm this, perform a test on your network using to see if you’re getting the correct speeds indicated on your monthly plan.

If not, restart your modem or router to re-establish the connection with your ISP. 

  1. Unplug your router’s power cable from the outlet. 
  2. Wait for at least five seconds. 
  3. Plug back in the power cable to restart your router.

See the steps below to flush your DNS: 

  1. Open the Start Menu by pressing the Windows key on your keyboard.
