In this article, we take a look at some of the common solutions to help you resolve the issue on your Minecraft server.

Why am I getting Connection closed message in Minecraft Bedrock?

• Server issues – Sometimes your server can encounter certain issues that are preventing you from joining it, so be sure to check your server configuration. Users reported An existing connection was forcibly closed by the remote host Minecraft on Aternos and Hypixel, but others are affected as well.
• Hardware resources – Minecraft can be demanding on your server, so make sure you have enough RAM.
• Network issues – Network issues, such as high ping or lag can lead to problems, so make sure that your connection is fast and stable. Not addressing these problems can lead to No Internet connection error in Minecraft.

How do I fix An existing connection was forcibly closed by the remote host in Minecraft?

Before we start fixing the issue, here a couple of simple checks to perform:

• Restart the server, client, and the network connection – Server glitches can cause problems such as these, so restarting your server occasionally can help. The same goes for your PC and network connection. To learn more about server issues, visit our Minecraft Server not working guide.
• Switch to Badlion client – Few users reported that the error doesn’t appear while using this client, so feel free to give it a try.
• Run server/client as administrator – Starting the server or the game as administrator can help sometimes. Also you can try using Java launched server instead of minecraft_server*.exe.
• Contact the server admin – If you’re getting this error while trying to join a server, it’s possible that server is having issues. Sometimes morph data can cause problems, but after an administrator clears it, the problem should be gone.
