And in this post, I am going to help you fix “io.netty.channel.abstractchannel$annotatedconnectexception: Connection Refused: no further Information” error.

So let’s begin.

​What Does Connection Refused Error means?

Connection Refused Error is a rare Error seen in the game “Minecraft” when you try to connect to a server.

It gets even worse when I say:

Connection Refused Error is not limited to a single server.

However, Minecraft users this days are facing this error frequently.

Over 90 Million gamers play Minecraft and among them almost 20% people face this connection refused error.

“io.netty.channel.abstractchannel$annotatedconnectexception: Connection Refused: no further Information” error may have multiple reasons to be triggered.

However, there are some common reasons too.

Let us know why this error is seen and how to fix such error codes in Minecraft.

What causes Connection Refused Error?

The main cause is the Common IP Connectivity issue.

But, after investigating a lot, I have come up with a conclusion that this error can be caused due to various reasons.

Let me explain:

Common IP Address Issue

While trying to connect to a server, due to the wrong IP address or the port, this error can be triggered in no time.

It is seen that, IP address attached with the correct port is used for forwarding your connection to the Minecraft server. 

In rare cases, the IP address changes from time to time and multiple users might get connected with the same IP address.

So, the IP address needs to be changed frequently to avoid such error.

Unstable Softwares

There are some software, which after installing it on your computer will conflict with the game.

As a result, Connection Refused Error will pop up.

You can check the list of the softwares that aren’t compatible with the Minecraft game.

VPN & Windows Firewall

Windows Firewall sometimes blocks Minecraft servers and for this reason you might be unable to connect to the server.

As a result, “io.netty.channel.abstractchannel$annotatedconnectexception: Connection Refused: no further Information” error pops out in your screen.

Same goes for VPN. Changing servers frequently using VPN’s may block the Host server.

Backdated Java software

Minecraft requires the latest version of JAVA in order to work properly. In case, if you have the latest application but have an outdated Java software, then chances are that certain elements will conflict with Minecraft.

As a result, you will see “io.netty.channel.abstractchannel$annotatedconnectexception: Connection Refused: no further Information” error.

There could be many other possible reasons But the above mentioned reasons are the most commonly noticed.
