Your computer may display this Minecraft server forcibly closed error as a result of two valid reasons.

Firstly, your Internet connection may not be strong enough to connect/remain connected to the server.As a result, you can’t connect to the internet with the connection that links you to the internet.The second reason for being unable to enjoy online multiplayer is problems on the server’s side. Usually, when the servers are under maintenance, you won’t be able to access them.

A lack of internet, weak network, router issues, or other computer or network-related issues may cause this. Your internet service provider can easily fix these issues. Here are some solutions to the An Existing Connection Was Forcibly Closed by the Remote Host error.

Ensure Your Network Is Stable 

The first thing you should check is that your network is stable. The most common reason behind facing this issue is the unstable network connection. You can check your internet speed on Fast.com.

If the speed is slow, then that means your network is unstable. Try fixing it and then check if you still face the issue or not. However, if there is no issue with the network, then head to the next troubleshooting step mentioned in this guide.

Turn Off Firewall

You may also face the issue because of Firewall being enabled. Try disabling the Firewall, and then check if you still encounter the error or not. To turn off Firewall, follow the steps given below-

Press the Windows key on your keyboard, and in the Start Menu, search for Firewall and network protection. Hit enter to open the Firewall settings.

 Next, click on your currently active network (public, private, or domain), and then turn off the toggle for the Windows Defender Firewall.

Now relaunch Minecraft and see if you still face the issue or not.

If you are using any third-party firewall or Antivirus with a firewall, then the firewall protection will be managed by that third-party application and not by Windows Security. Disable the third-party firewall if you are using one to fix the issue. If disabling the Firewall works, you will have to disable public access for Java Platform SE Binary. To do so, follow the steps given below-

Open the Start Menu by pressing the Windows key on your keyboard. In the Start Menu, search for Control Panel and open it.

Click on System and Security in the Control Panel. Under the Windows Defender Firewall, click on Allow an app or feature through Windows Firewall.

Change Server Side View Distance
