Before we begin with the fixes, it is important to identify the root cause of the issue. There are multiple reasons why an existing connection was forcibly closed by the remote host error that appears when you play online. The majority of those reasons are – 

  1. A PC security program does not allow network access to the game. 
  2. There is an error with your DNS that cannot connect to the game server. 
  3. Java settings on your PC are not updated to support your game properly.
  4. Registry optimization is required to handle the Minecraft process efficiently.
  5. An outdated network adapter driver is causing the connection to shut down. 

These errors and the fact that your PC cannot connect to the internet properly are the root cause of an existing connection being forcibly closed by the remote host error in Minecraft.

Now that we have identified the causes, the next move is to support these causes with relevant fixes. Let’s look at some of the fixes you can use to resolve these potential issues on your Windows PC. 

5 Fixes to Help You Resolve Remote Host Errors on Minecraft

Fix #1 – Optimize Your System Registry

You should optimize your existing registry files on Windows. These registry files usually contain configuration information for any process. If the internet is continuously being disconnected from your device, there are solid chances that the issue lies in the registry. 

Fragmentation in registries is one of the most common errors that cause them to malfunction. Optimization can help gather the scattered registry files and defrag the existing ones. 

However, playing around with the Windows registry can become risky, as a slight misconfiguration might cause an inevitable error. Hence, you can use Advanced System Optimizer to scan the registries for issues and optimize them immediately. 

Before fixing invalid registry entries, the tool takes a backup as a precaution.

Fix #2 – Try Changing Your DNS Server

The domain name server your PC is using might be unable to find the required configured cache. This often happens due to a slow internet connection, which might also be a consequence of using a slow DNS server by your ISP. 

The best thing you can do is change your DNS server to a more reliable and speedy server. 

To do so – 

Step 1 – Press Windows + I to open the system settings

If this method seems too much work, you can choose a different method to change your DNS server on Windows

The Windows Firewall is the backbone of your PC’s security. Turning it off might put your PC to risk of getting exposed to malicious software. Hence it is advised that you perform this step at your own risk. 

Sometimes, the firewall detects your game server as harmful and instantly disconnects you from the connected server. Due to this, you might have encountered the “An existing connection was forcibly closed by the remote host” error on your PC out of nowhere.

Here’s how to turn off the firewall on your Windows PC –
