Follow the solutions shown below to easily solve the existing connection was forcibly closed error.

1. Check The Internet Connection

If you are forcibly disconnected from the Minecraft server, check your internet connection first.

Click here to check the speed of your internet connection.

Also, restart your modem or router following the steps given below:

Turn off your modem or router, then unplug all the power cables.
Wait for 5-10 minutes and then reconnect everything.
Restart your PC, turn on the router or modem, and connect to the internet. Now try to connect to the Minecraft server.

If the problem persists, go to the next solution.

2. Turn Off Windows Firewall

Sometimes firewall interferes with Minecraft and creates issues. So block the Firewall temporarily and check if this can fix the problem.

To do that, follow the steps given below:

Search Windows Defender Firewall in the Windows search bar and select the first option.
Select the Turn Windows Defender Firewall on or off option from the left panel.

From the next window, check the box for Turn off Windows Defender Firewall (not recommended) for private and public network settings.

Find Java™ Platform SE Binary and check the private and public boxes.

Click on the OK button to complete the process. If you are using any other Firewall, disable that too.

In the Advanced network settings section, click on the Change Adapter options.

Right-click on the Network Connection and open Properties.
