[FIXED] io.netty.channel.abstractchannel$annotatedconnectexception

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

What is io.netty.channel.abstractchannel$annotatedconnectexception error?

In a nutshell, it is a connection error, where your device tries to connect to your minecraft server and due to the server you are connecting to, it somehow doesn’t remember your request or doesn’t receive the minecraft signal.

What causes the Minecraft io.netty.channel.abstractchannel$annotatedconnectexception error?

After receiving various reports from many users, we analyzed the issue and created a variety of solutions that resolved the issue for most users. We also investigated the reasons for the error and listed them below. That is why:

IP problem: In some situations, the problem occurs due to an incorrect IP address or port when 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 assigned to you by your ISP may 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 softwareNote: There is a list of software that may not be compatible with Minecraft, causing problems if installed on your server computer. Minecraft has an official list of non-game apps causing conflicts.

firewalls: You can also block your link to the server with the windows firewall you are using. For the game to successfully connect to the server, Java and the game directory must be added to the Windows Firewall exclusion list.

Java deprecated: Minecraft needs to modify the current version of the Java program to work properly. It can cause conflicts with some elements of the game and prevent proper connections to the server if Java is outdated and the launcher is modified to the latest versions.

We’ll move on to 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’s start with some simple solutions that work with almost any error to solve this problem. Don’t miss them unless you have already tried them because these are the best solutions that take less time!

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

Time to take a couple more advanced steps if they didn’t help.

To start figuring this out, we first need to decide which address we should take, which depends on who is running the server you’re trying to connect to, if it’s your own server.

Solution 1 – Add exceptions to the firewall settings in the Minecraft folder

Adding exceptions to the Firewall configuration is the only way to fix the connection timed out in io.netty.channel.connecttimeoutexception. As I described above, you can often prevent the VPN and Windows Firewall from accessing the Minecraft game server. Added several exceptions to Firewall to prevent a noted connection channel link refused error.

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

You can now open the Minecraft launcher to see if the bug is fixed or not.

Solution 2: Reset the router

Resetting the router is a simpler resolution, and some players can fix the io.netty channel error. You can do this by disabling and unplugging the router. Then plug in the router and activate it in a few minutes.

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

To press the reset button on a router, a paperclip is usually needed. Note that resetting a router also removes all custom settings for this purpose.

Solution 3 – Add the IP address and port

If you are not using a static IP address, it will be adjusted every few days or when the Internet connection is restored. Therefore, we will check the IP and port of the game at this stage and add it to our Minecraft Launcher.

Solution 4: Check port filtering

We found several cases where users accidentally leaked ports. Even if port forwarding works correctly, it is immediately canceled by filtering and you cannot connect to the Minecraft servers.

Here, you can check the network settings of your router and your local machine and make sure that port filters are not enabled, and if not, that the correct ports are being filtered.

Solution 5: Check ISP network access

You can check your ISP’s network access if none of these methods work. ISPs often block and do not allow you to transfer network access to particular domains. Contact your ISP to ensure that 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 your ISP is probably blocked and you need a network update.

Solution 6 – Remove unstable software

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

Remove fake plugins and just install 100% authenticated plugins. If you don’t know which music plugin you can legally and easily use, look for the best music bots from your minecraft server.

Digital Ethernet with Hamachi is one of the incompatible applications. In this case, disabling or removing the software will be smart enough.

Open the ipconfig prompt and type. Find a Virtual Ethernet Hamachi Link configuration. Note the addresses and go to the Hamachi search panel of the Virtual Ethernet application to uninstall it.

Add your server IP and port number and fix minecraft network problem. You can also set up a Hamachi server if you intend to play with your peers.

Solution 7 – Use a trusted VPN connection source

Do you want to play Minecraft in your breakfast but still block it? Check out the best Minecraft VPNs for easy server access.

Minecraft may be banned in your area. Often the Minecraft servers are blocked in the Windows Firewall, so you can’t connect to the site. This is the same for VPN. Host server may be blocked by changes in servers often using VPN.

Reliable VPN apps that don’t block your Minecraft game server can be used to give it a try. You can easily resolve io.netty.channel.connecttimeoutexception just by changing the area.

Solution 8: Update Javasoftware

To work properly, Minecraft needs the latest JAVA update. Missing items conflict with Minecraft when trying to connect to a server using the outdated Java program. Consequently, you will not see any more details rejected by the java.net.connecttception connection.

No more errors detailed more clearly on Windows 10 at java.net.connectexception connection timed out. To enter a Minecraft server, you must have a Learn to Mod account. The Minecraft error implies that you don’t have a “learn to mod” account in java.net connecttexception. The JAVA program can be updated to its latest edition.

Solution 9 – Reinstall Minecraft

Often your game data is perceived as corrupted and causes a lot of issues like connection errors. Uninstalling Minecraft can help you solve the problem and simply provide you with a fresh installation.

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

Get the latest version of Minecraft and try to connect to the game server to fix the network channel noted connection exception.


Hopefully, these solutions helped you fix the io.netty.channel.abstractchannel$annotatedconnectexception error and allowed you to play Minecraft again. If not, you may want to check out the Minecraft forum for more information.
