Minecraft has become extremely popular in the online gaming community, with over 91 million users from all around the world. This figure represents the amount of players who log in on a monthly basis. Minecraft is, without a doubt, one of the most popular platforms available.
Many users, on the other hand, complained about the error they were getting when trying to connect to a server. The problem “io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no additional information” does not affect just one server, but all of them.
What Is The Cause Of io.netty.channel.AbstractChannel$AnnotatedConnectException?
Following that, after obtaining numerous reports pointing to the same issue from a variety of users, we were forced to investigate the causes of this error as quickly as possible. Here are the factors that resulted in this inaccuracy.
Read them attentively so that you may move forward with confidence in resolving the problem.
1. Install a Firewall
To connect the game to the server effectively, you must add all of the game directories, as well as the Java files, to the Windows Firewall’s exclusion list. Because there’s a chance that the Windows Firewall you’re using is preventing you from establishing a connection to the server.
2. Software That Is Incompatible
Minecraft features an official list of software that is incompatible with the game. If these are downloaded and installed on the machine from which you are attempting to connect to the server, they can cause conflicts and difficulties.
3. IP Address Problems
When attempting to create a connection with the server, you may see this error if you use the wrong IP address or the listed port. Unless you utilise a static IP address, which is uncommon because the IP address assigned to you by your ISP frequently changes.
It’s possible that numerous users will be assigned the same IP address. As a result, you must change your IP address on a regular basis. The reason for this is because while sending the connection to the server, the IP address as well as the true port are used.
4. Java That Is No Longer Supported
If the system’s Java is out of date, but the launcher is up to date, there may be issues with specific game elements. As a result, the server connection is disrupted. As a result, in order for Minecraft to function properly, it needs to be running on the most recent version of Java software.
How to Fix “io.netty.channel.AbstractChannel$AnnotatedConnectException
Error with AbstractChannel$AnnotatedConnectException. Now, go through the solutions in order to avoid any potential roadblocks.
1. Reset The Internet
The ISP’s given IP address is changed. Unless you utilise a static IP address, whenever your internet router is rebooted. By power cycling the Internet Router, we are entirely reinitializing the DNS cache and internet settings in these steps. Take the following steps:
Step 1: Turn off the power to the internet router.
Step 2: After waiting 5 minutes, reconnect the power connection.
Step 3: As soon as you have internet connectivity, try to connect to the server. Check to see whether the issue still exists.
2. Restart Your Modem
It’s possible that your Internet modem/router is causing you troubles. It’s at this point that you’ll notice the error “io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no additional information.” Follow these procedures to fix it in Minecraft:
Step 1: Turn off your Router for at least 5 minutes. Restart the router by turning it back on.
Step 2: If the power-off procedure does not work, try resetting all of the router’s settings and starting over.
These steps may be very helpful in resolving the Minecraft server connection issue.
3. Create a Firewall Exception
As previously mentioned, it’s possible that the Windows Firewall you’re using is preventing you from connecting to the server. As a result, these are the steps to add an exception in the Firewall for certain of the Minecraft executables that require internet connectivity. Take the following steps:
Step 1: To begin, go to the Start menu and select the Settings icon.
Step 2: Select Updates & Security from the Settings menu.
Step 3: Select “Windows Security” from the left-hand menu. Select “Firewall & Network Protection” from the drop-down menu.
Step 4: Scroll down and pick “Allow an App Through Firewall” from the drop-down menu.
Step 5: Select “Change Settings” from the drop-down menu and select “Yes” from the warning box.
Step 6: From the list of options, select “Allow another app” and then “Browse.”
Step 7: Select the game as well as the launcher executable from the game installation directory.
Step 8: Go through the preceding steps again, but this time navigate via the directory where you installed the Minecraft servers.
Step 9: Open the “Maxwell” and “Minecraft Server” folders, in that order.
Step 10: Allow all Java executables in the folder to run in the same way.
Step 11: Restart the process, but this time instead of hitting “Allow another app” after selecting the “Change” option, simply browse down the list of apps now available. Both the “Private” and “Public” networks can now use all of the “Java Platform SE Binary” settings.
Step 12: Finally, launch Minecraft and try to connect to the server using the launcher. Check to see if the error still exists.
4. Add The IP Address and Port
If you don’t use a static IP address, it will change every two to three days. When your Internet Connection is reset, you will see this. We will check the IP address as well as the authentic port for the game using these techniques.
Then, in the Minecraft Launcher, add them. As a result, pay close attention to the following steps:
Step 1: From the Windows toolbar, go to the search box and type “Command Prompt.”
Step 2: Select “Run as Administrator” from the context menu when right-clicking on the icon.
Step 3: Write down the “IPV4 Address” after typing “ipconfig.”
Step 4: Go to the “Minecraft Servers folders à Maxwell (some random numbers) à Minecraft Server” folder. Open the text document “Server Properties.”
Step 5: Make a mental note of the “Server Port” that appears on the screen. In this case, it’s “25565,” and it should be the same in all cases. In other circumstances, though, it may be different.
Step 6: Launch Minecraft and go to the “Play Multiplayer” option.
Step 7: By clicking on the server you want to connect to, you may choose the one you want to connect to. Select “Edit” from the list of options below.
Step 8: The server’s name can be whatever you want it to be. As previously stated, the “Address” must be an IPV4 address. The port number, for example, “XXX.XXX.X.X:25565,” where “25565” is the port number, may change.
Step 9: After clicking “Done,” click “Refresh.” Check to see if the error still exists.
There are several applications that aren’t normally compatible with certain Minecraft things. They may result in errors. The following lists are accessible in Minecraft and can be used to learn more. You will always encounter this issue in the game if they are downloaded or installed on the PC from which the server is running.
5. Uninstalling Conflicting Software
Some software interferes with the Minecraft servers’ usual operation. The Virtual Ethernet with Hamachi is one of them. Follow these procedures to uninstall or disable the software to be on the safe side and avoid any additional errors.
Step 1: At the command prompt, type “ipconfig.” Virtual Ethernet Connection with Hamachi appears as a configuration. Please make a list of all of the addresses.
Step 2: Now go to the Search Panel and delete Hamachi’s Virtual Ethernet Connection.
Step 3: Then, on the Minecraft server, provide your appropriate port number and IP address. Now you must fix the Minecraft io.netty problems.
Step 4: Continue to the following step to learn how to add the IP address and port number to your Minecraft server.
6. Select The Best VPN
If Minecraft is prohibited in your area, you can use Minecraft Servers. Otherwise, choose a reputable VPN provider. They will not prevent you from accessing the Minecraft server.
The error “io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no additional information” may be resolved simply by changing the region.
7. Reinstall Minecraft
You can apply this method if your Game Data becomes corrupted, resulting in issues such as the “io.netty.channel.” An error occurred when the AbstractChannel$AnnotatedConnection timed out. This problem can be resolved by uninstalling Minecraft and reinstalling it on a new computer.
Follow the steps below to do so:
