How to Fix io.netty.channel.abstractchannel$annotatedconnectexception in Minecraft
The server from which a connection has timed out is not fixed. To join a multiplayer game server, most people get an error notice. The IP connectivity problem is the root cause of the io netty.channel error.
Other possible problems include outdated Java software, Windows Firewall blocking of servers, and unreliable software.
Because the IP address of the port was wrong, io.netty.channel.abstractchannel didn’t work because it didn’t work. An error in Minecraft can happen in no time at all. It can be seen that the IP address with the correct port is used to send your connection to the client server. This isn’t always the case. The IP address might change from time to time, and multiple people might be able to connect to the same IP address.
At first, it may seem hard to you. It’s still worth reading, though, because you can fix Minecraft’s abstract channel error in just a few minutes.
In order to fix minecraft io.netty.channel.abstractchannel$annotatedconnectexception connection refused error, follow these steps:
Method 1. Reset Router
Resetting the router is a simple way to fix the io.netty channel error for some people. If you want to do that, you can turn the router off and remove the power cord. So plug in your router again and turn it on after a little while.
Some people have also said that factory resetting their routers worked for them. To factory reset a router, press and hold its reset button down for 10 to 30 seconds, then turn it off and on again.
In most cases, you will need a paperclip in order to press a router’s reset button. If you reset a router that way, you’ll lose all of the settings you’ve made for it.
Method 2. Check the firewall’s app permissions
The io.netty.channel error is often caused by the Windows Defender Firewall blocking Minecraft’s connection to the servers.
1. Go to the Windows search bar and type “firewall” as the search keyword in the text box. Select Windows Defender Firewall from results.
2. Select Allow an App through the Firewall option.
3. Click Change settings to change the firewall settings.
4. Navigate to the game installation directory folder and select the launcher executable.
5. Repeat Steps 2 & 3 again but this time, go to the directory folder in which you have the servers of Minecraft installed.
6. Go to the Minecraft servers folder maxwell (Minecraft Server folder).
7. Repeat the process and allow the Java executables located inside the folder.
8. Repeat step 3 and instead of clicking Allow another app, scroll down to the list of Java Platform SE Binary.
9. Next, select all the Public and Private check boxes for Java Platform SE Binary options.
Now, you can launch the Minecraft launcher to see if the error has been fixed or if it hasn’t.
An important thing to remember: Due to LAN issues, Minecraft Lan io.netty.channel.abstractchannel$annotatedconnectexception disconnection can appear. Check out our separate post to fix Lan not working in Minecraft.
Method 3. Add IP Address and Select the Suitable Working Port
Connect to the Minecraft servers with your IP address and port number. Problems with Minecraft’s connection being rejected may arise if your IP address and port are both dynamic. It is possible to fix the minecraft.io error by changing your IP address and entering it into the Minecraft Launcher. Port forwarding is a good option. Using the command prompt, you can also see what your IP address is set to.
Add an IP address and select a functioning port as follows:
1. Open Command Prompt as Administrator as Administrator.
2. In the command prompt, type ipconfig and press Enter. Then, write down your IPV4 address
3. Go to Minecraft Servers folder > Maxwell (Minecraft Server folder) > Minecraft Server at the same time and open Server Properties text document.
4. Write down the Server Port and open up Minecraft and navigate to the Play Multiplayer option.
5. Choose the server you want to join and click Edit.
6. Enter the IPv4 address and select Done. Connect to a server using this IPv4 address.
7. Refresh to apply changes.
In addition to the Minecraft Resolver tool, you can also use it to fix Minecraft’s memory issues.
Method 4. Update Java software
Minecraft needs the most up-to-date version of JAVA to work properly. You can’t use old Java software. The Minecraft game won’t work properly if you have outdated Java when you try to connect to the server. Eventually, you will see java.net.connectexception connection refused no further information.
In particular on Windows 11/10, the Java.net.connectexception connection timed out with no more information issue occurs. To join a Minecraft server, one must have a Learn to Mod account. If you receive a Java.net connectexception minecraft error, it signifies you do not have a Learn To Mod account. JAVA can be updated to the most recent version to fix the problem.
Final Thoughts
Connection refused: no further information error is a major setback. This error will never come up again once you’ve figured out what’s causing it. If none of the above solutions worked for you, I would recommend that you fix your LAN card to see if this error disappears or not.
