  • Windows Network Drivers – Having unsupported or outdated network drivers can also cause Unexpected Server Error on Overwatch 2.
  • Update Windows – In most cases, outdated windows can also interfere with the proper execution and working of the latest applications or video games which can also cause this issue.
  • Windows Compatibility Settings – Not having proper administrative privileges can make Overwatch 2 not launch properly or connect to servers, causing this issue.
  • Port Forwarding – Restricted or Blocked network ports from Windows Firewall can also act as a shield when trying to connect to Battle.net servers. They can cause server Errors when trying to play Overwatch 2.
  • Keep Restarting The Game – This error code can also be fixed by restarting the game once the error appears.
  • Fresh Install Battle.net and Overwatch 2 – Uninstalling the previous iteration of Battle.net along with the Overwatch 2 files and installing a fresh copy can also solve many errors/glitches.

1. Keep Restarting Overwatch 2

Many users experiencing technical issues on Overwatch 2 have notified several fixes through various forums and Reddit to help eliminate the server error on Overwatch 2, among many other randomly occurring errors.

This is primarily because with the launch of Overwatch 2, players of the original game have flooded to give this one a try, and the servers are often overloaded. If you experience any kind of server-side errors, including but not limited to Unexpected Server Errors, then you can just shut the game down, restart the launcher and keep trying to launch the game. Most of the time, these server-sided errors are bound to disappear after 7-8 tries.

2. Change Battle.net Region Settings

Blizzard Global Play allows its users to change the servers/regions of all the games available on Battle.net, which helps by making it easier to troubleshoot if the server is glitching/unstable due to various reasons. It can also help by allowing players from different parts of the world to play with each other. There are currently three regions available to regular players:

  • Americas: which includes North America, Latin America, South America, Australia, and New Zealand.
  • Europe: which includes European Union, Eastern Europe, Russia, Africa, and the Middle East.
  • Asia: which contains players from South Korea, Taiwan, Hong Kong, and Macau.

Changing regions is instead a straightforward and effortless task. To change the Battle.net region/server, follow the steps below:

  1. Open the Battle.net launcher and log in using your credentials.
  2. Select the game from your library that you want to troubleshoot, which in this case is Overwatch 2.
  3. Click on the globe icon over the Install/Launch button
  4. Change to your desired Region and restart the Battle.net Launcher
    Change Battle.Net Region

3. Add A Firewall Exception

Windows 10/11firewall usually works as a gatekeeper and blocks unused network ports, which disables particular applications from communicating over the Internet. Battle.net servers are pretty prone to this instance, and thus. As a result, Overwatch 2 can easily crash or have multiple problems regarding the Internet, including Overwatch 2 Unexpected Server Error. To fix this, you need to allow Battle.net and Overwatch 2 through Windows 10/11 Firewall so they can easily communicate with the Blizzard servers. Follow the steps below:

  1. Open Start Menu and Type Windows Defender Firewall

    Start Menu To Windows Defender Firewall
  2. Launch it and click Allow An App Or Feature Through Windows Defender Firewall

4. Disable Antivirus Real-time Protection

If you are using any third-party Antivirus Real-time Protection or even a Windows 10/11 built-in Windows Defender/Security, then it can block a particular application or video game from launching or communicating with the server. Antivirus Real-time Protection can result in many network-related issues, including lags, ping spikes, packet loss, server connection loss, or even game crashing.

To fix this issue, you can turn off the Antivirus Real-time Protection so Battle.net and Overwatch 2 can have direct and uninterrupted communication with the server, making your game run without lag or crashes. To do so, follow the instructions below:

6. Disable Any Built-In Or Third-Party VPN

Many users have reported issues when they try to play Overwatch 2 or any other game on Battle.net while connected to any third-party or Windows built-in VPN.

Since online video games require a direct and uninterrupted connection from your computer to the game server, it can lead to many issues like routing you to a bad server, which makes your game unplayable due to high ping spikes, packet loss, server disconnects, or Overwatch 2 crashes. To fix this, you can turn off Windows built-in VPN by following the guide below:

8. Update Windows To The Latest Version or Build

Outdated Windows OS can also create many conflicts when an application or video game tries to launch or connect to the game server through its online services. Keeping your Windows OS updated to the latest stable build from the official Microsoft Windows Check for Updates Tool is always a good idea.

Many latest applications or video games require Microsoft Windows to be updated to the latest stable build to execute and function appropriately as the developers of that particular application or video game intended.

9. Network Port Forwarding

Many video games communicate to their specific servers through unique Network ports for speedy and uninterrupted service to provide the user with the best possible experience. These applications or video games require these particular ports to be unblocked so that they can access them without any issue.

10. Change DNS Server

Windows OS automatically allocates a default DNS address based on your location and internet preferences to provide you with the best possible route to access the Internet. But more often than not, it’s not the correct one. 

Changing your DNS manually to either Google DNS or Cloudflare DNS is a better practice. It should be encouraged to be performed on any device that needs to be connected to the Internet, regardless of its type or configuration. To change your DNS to Google or Cloudflare, follow the instructions below:

  1. Click on Start Menu and open Settings
    Opening Windows 11 Settings From Start Menu
  2. Click on Network and Internet, then navigate to Advanced Network Settings

    Network and Internet To Advanced Network Settings
  3. Scroll Down and click More Network Adapter Options

    Opening More Network Adapter Options
  4. Right-click on your active Internet connection and click Properties

    Opening Network Connections Properties

    Change Automatic DNS Server To Cloudflare DNS Server

11. Turn On Static IP

Your Router always allocates you the different IP addresses depending on the number of devices connected to your Router hence the name “Dynamic IP Address.” A Static IP Address allocates a unique set of IP addresses to all your devices and doesn’t change when that particular device is shut down or disconnected from the Internet.

You can change your IP address from Dynamic to Static IP Address by requesting it to your Internet Service Provider, but that usually costs extra in most scenarios. An advanced solution can allocate your Windows-based PC a Static IP address without extra cost. Follow the steps below to change your Windows-based PC from Dynamic to Static IP Address:

  1. Open Start Menu and click Settings

    Opening Windows 11 Settings From Start Menu
  2.  Select Network and Internet from the left sidebar and click Advanced Network Settings

    Network and Internet To Advanced Network Settings
  3.  Navigate to the bottom and click More Network Adapter Options

    Opening More Network Adapter Options
  4.  Right-click on your working Internet connection and select Properties

    Opening Network Connections Properties
  5. Go to Internet Protocol Version 4 (TCP/IPv4) and click on Properties

    Opening Internet Protocol Version 4 (TCP IPv4) Properties
  6. Now press Win+R, type CMD and press OK

    Windows Run CMD Command
  7. Type ipconfig in the Windows Command Prompt and press Enter

    Windows Command Prompt IPCONFIG Addresses
  8. Copy the IP Address, Subnet Mask, and Default Gateway into the Internet Protocol Version 4 (TCP/IPv4) properties, and press OK.

    Internet Protocol Version 4 (TCP IPv4) Static IP

12. Change Router Settings

Since every Router contains different settings, you should consult your router manufacturer or a professional technician to help optimize the Router to your desired settings. It will provide the best quality of uninterrupted Internet connection to your PC so you can enjoy your favorite titles in peace.
