How to Fix io.netty.channel.abstractchannel$annotatedconnectexception in Minecraft

Minecraft is a sandboxing game that Mojang has developed and published. The game came out in 2011 and became popular immediately in the online gaming community. It has one of the highest counts of players with 91 million monthly players. Recently, however, several reports came from users who experience the “io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no further information” error when attempting to connect to the server. This error is not restricted to and continues to occur on one single server.

What is io.netty.channel.abstractchannel$annotatedconnectexception Error

Simply put, it’s an error of connection, where your device tries to connect to your Minecraft server and because of the server you are connecting to, you somehow do not remember your request or do not get the signal back to Minecraft.

What Causes the Minecraft io.netty.channel.abstractchannel$annotatedconnectexception Error?

After several reports have been received from many users, we analyzed the problem and created a variety of solutions that solved the problem for most users. We also investigated the reasons for the mistake and listed them below. That is why:

IP Problem: In some situations, the problem occurs because of the incorrect IP address or port while connecting to a server. When the server is accepted the IP address along with the correct port is used to forward your connection to the server. If a static IP address is not used, the IP address allocated to you by the ISP can change from time to time and the same IP address may be assigned to multiple users. This means that from time to time, the IP address must be edited.

Incompatible Software: There is a list of software that cannot be Minecraft compatible, causing problems if installed on your server’s computer. Minecraft has an official list of non-game and conflict-causing apps.

Firewall: You can also block your link to the server with the Windows firewall you are using. In order for the game to connect to the server properly, Java and the game directory must be added to the Windows Firewall Exclusion List.

Java Outdated: Minecraft needs the current version of the Java program to be modified to function correctly. It can cause conflicts with some elements of the game and prevent proper connections with the server if the Java is obsolete and the launcher is modified to the latest versions.

We will move on toward solutions now that you have a basic understanding of the essence of the problem. These solutions should be used to ensure that there are no contradictions with the precise order in which they are presented.

What is the solution to this error?

Let us start with some simple solutions that function on nearly any mistake to solve this problem. Don’t miss them unless you’ve tried them already because these are the best solutions that take the least time!

• Minecraft reboot.
• Reset your PC. •
• Turn off the power of your router for a minute and restart it again.

It’s time to take a couple of the more advanced steps if they didn’t help.

To begin solving this, first, we have to decide which direction we have to take, which depends on who runs the server to which you are trying to connect, whether that’s your own server.

Solution 1: Add Exceptions to Firewall Settings in Minecraft Folder

Adding Firewall settings exceptions is the only way to repair the connection timed out of io.netty.channel.connecttimeoutexception. As I described earlier, you can often avoid the VPN and Windows Firewall accessing the Minecraft game server. Added several exceptions to Firewall in order to prevent a rejected link error of the annotated connection channel.

  • Clicking on the Updates & Protection option, go to the Windows search bar.
  • Select the option Firewall & Network Safety in the left pane of the Windows Security panel.
  • Download and select Activate the firewall option for an app.
  • Select Yes and press the Change Settings option.
  • Select Again the Allow option for another app.
  • Pick the launcher executable to browse the folder for game installation.
  • Again, repeat Phase 5&6, but search the folder directory where you have Minecraft servers installed.
  • Open the maxwell folder of Minecraft servers.
  • Repeat the process and allow Java executables in the folder.
  • Repeat Phase 4 and simply scroll down to the Java Platform SE binary list instead of clicking on Enable another app.
  • Enable all the SE binary options for the Java platform via public and private networks.

Now the Minecraft launcher can be opened to see whether or not the error is fixed.

Solution 2: Reset Router

Resetting the router is a simpler resolution, and some players might correct the io.netty channel error. You can do so by disabled and disconnected the router. Then plug in the router and trigger it within a few minutes.

Some users have stated that the resetting of their routers solved the problem for them. Press and hold down the reset button for 10-30 seconds to reset an installation router.

To press the reset button of a router, a clip is typically needed. Note that resetting a router also deletes all custom configurations for this purpose.

Solution 3: Adding the IP address and port

If you are not using a static IP address, it will adjust every few days or when the Internet connection is re-established. Therefore, we will check the IP and port for the game in this phase, and add it to our Minecraft Launcher.

Solution 4: Checking for Port Filtering

We find several cases in which users filtered ports accidentally. Even if the port forwarding works correctly, the filtering immediately cancels it and you cannot connect to Minecraft servers.

Here, you can check the network configuration of your router and your local machine and ensure that port filters aren’t enabled, and if they aren’t, the right ports filtered.

Solution 5: Checking ISP Network Access

You can verify your ISP network access if none of these methods works. ISPs often block and don’t allow you to transfer network access to particular domains. Contact your ISP to make sure internet access is not currently blocked.

You can even change your internet connection to see how it works for you on your 3G smartphone. If so, it means that you probably block your ISP and need a network update.

Solution 6: Delete Unstable Software 

There is some unstable software that will interfere with the game after it has been installed on your computer. On several websites, you can access the list of software that is not Minecraft compatible.

Delete false plugins and just install 100% authenticated plugins. If you do not know what music plugin you can then use legally and easily, search your Minecraft server’s best music bots.

Digital Ethernet with Hamachi is one of the incompatible applications. In this case, the deactivation or deletion of the software will be wise enough.

Open the ipconfig prompt and type. Find a Virtual Ethernet Hamachi Link configuration. Please note the addresses and go to the Virtual Ethernet App Hamachi search board to uninstall.

Add your server IP and port number and fix the ionetty problem of Minecraft. You can also set up a Hamachi server if you try to play with your mates.

Solution 7: Use a Trusted VPN Connection Source

You want to play Minecraft on your breakfast but you’re still blocking it? Check out Minecraft’s best VPNs for access to the server easily.

Minecraft in your area can be prohibited. Often Minecraft servers are blocked in Windows Firewall, which is why you cannot connect to the site. This is the same for VPN. The Host server may be blocked by changes in servers often utilizing VPNs.

Trusted VPN applications that don’t block your Minecraft game server can be used to try. You can easily resolve io.netty.channel.connecttimeoutexception by simply changing the area.

Solution 8: Update Java software

In order to function properly, Minecraft needs the latest JAVA update. The missing elements are in conflict with Minecraft when you try to connect to a server using the obsolete Java program. Consequently, you won’t see any more details refused by the java.net.connecttexception connection.

No further detailed errors are more clearly noted in Windows 10 on Java.net.connectexception connection timed out. To enter a Minecraft server, you have to have a Learn to Mod account. Minecraft error implies that you do not have a “learn to mode” account on Java.net connecttexception. The JAVA program can be upgraded to its latest edition.

Solution 9: Reinstall Minecraft

Often your game data is perceived as corrupt and causes a lot of issues, such as connection errors. Uninstalling Minecraft can help you solve the issue and simply providing a new installation for it.

You must navigate to the Control Panel>Uninstall a program>Select Minecraft to uninstall Minecraft.

Get Minecraft’s latest version and attempt to connect to the game server to correct annotated connectexception of the netty channel.

Conclude

Hopefully, these solutions helped you fix the io.netty.channel.abstractchannel$annotatedconnectexception error and let you get back to playing Minecraft. If not then you might want to take to the Minecraft Forum to find some more information.
