What is causing the error io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no further information on Minecraft

Sometimes Windows firewall blocks the connection to the Minecraft server, and this causes the error. For playing Minecraft, it is necessary to add the Java files and the game directory into the exclusion list of Windows Firewall in order for the game to connect to the server.

Reason 2: Outdated Java

All Minecraft users need the latest version of Java to run the game properly. If the game version differs from the java version, then the error might occur. In other words, if you have the latest version of the game and the launcher and an older version of Java, then you cannot play the game.

Reason 3: IP issue

Sometimes, the reason for the error is the wrong IP address or the port listed while trying to connect to a game server. When you launch the game, the IP address, along with the correct port, is used to forward your connection to the server.

In some cases, the IP address assigned to you by your ISP changes from time to time, and because of this, multiple users might be allocated the same IP address. Therefore, the IP address needs to be edited from time to time in order to play the game without any issues.

Reason 4: Incompatible Software

There are a few software that is not compatible with Minecraft. If these type of software are installed in your system, then they may prevent Minecraft from running properly. You can use Google search to get information about this software easily as Minecraft has created a list for such software.

That’s all now. At last, Open the Minecraft launcher, try to connect to the server. Check to see if the issue still persists.

Method 3: Adding the IP address and port

As we mentioned above, you need a static IP address in order to play the game because if an IP address is not Static, it changes every couple of days, and whenever the Internet is reset. In this solution, we are going to be checking the IP address and the correct port for the game, and after that, we will add it to the Minecraft Launcher to prevent the error.

First of all, click on the search bar or use Cortana to open  Command Prompt.

Select the command prompt option from the search results and Right-click on it and select Run as Administrator.

After opening the Command prompt, type in ‘ipconfig’ and note down the IPV4 Address from the result.

After that, go to the Minecraft Servers. Follow the below path to do it.
folder>Maxwell (any type of random numbers)> MinecraftServer
Now, open the Server Properties text document from it.

Note down the Server Port listed in the document. In our case it the server port is 25565.

Now open up the Minecraft game and go to the Play Multiplayer option.

After that, select the server which you want to join by clicking on it. Select the Edit option from the below options.

The server name can be according to your choice. However, the Address needs to be the IPV4 address that we noted. and the port number also needs to be the same as we noted in our case; it is the 25565.

At last, click on Done and click on the Refresh option and, at last, check to see if the issue persists.

Method 4: Checking for Port Filtering

We came across some cases where users were accidentally filtering the ports. Even though the port forwarding was working just fine, the filtering automatically nullifies it. Because of this, you will not be able to connect to the servers and face the errors.

In such cases, what you can do is check your router’s and your local machine’s network configurations. Always make sure that port filtering is not turned on. If it is turned on, the correct ports are being filtered, and you need to turn it off.

Method 5: Checking ISP Network Access

If none of the above methods works, then it is most probably the ISP issue. You should check your ISP’s network access as some ISPs sometimes block network access to specific domains. Because of it, you can not access some servers. To solve it once, Contact your ISP and verify.
