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:
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:
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:
5. Update Outdated Network Drivers

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

To fix this, you can turn off Windows built-in VPN by following the guide below: Note: If you have any third-party VPN, you can turn it off by following the instructions from its website.
7. Apply Optimized Windows Compatibility Settings

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Outdated Windows OS can also create many conflicts when an application or video game tries to launch or connect to the game server through its online services.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.

Port forward is a more advanced form of Windows Firewall, and you can block or unblock these specific ports manually by following the steps below:
Opening Inbound And Outbound TCP Ports
Opening Inbound And Outbound UDP Ports
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:
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:
