What Causes Connection Refused Minecraft Error?

The most common cause of this error in Minecraft is the IP connectivity issue. But there are a lot more reasons why this error occurs. Today, we are going to give you detailed information on some more common causes of connection refused error. Some of them are.

1. Common IP Address Issue

This is the most common error faced among users. This error is triggered due to the wrong IP address of the port while connecting to a server.

It happens because the IP address connected to the correct port is used for forwarding your connection to the servers of Minecraft. But in some cases, the IP address changes from time to time, and sometimes different users get connected with the same IP address.

2. Unstable Software

If you get an abstract channel error in Minecraft, it means that you have some unstable software installed on your PC. This unstable software installed on your device can conflict with the game causing an error.

You can google and check the list of software that isn’t compatible and causes an error with the Minecraft game.

3. VPN & Windows Firewall

Sometimes Windows Firewall blocks the servers of Minecraft, which prevents you from connecting to the server. This triggers io.netty.channel.abstractchannel$annotatedconnectexception error.

Using a VPN causes the same problem. Due to regular changes in severs using VPN, it may block the host server. You might not want your servers to get banned to so recommend you to avoid usage of VPNs.

4. Outdated Java Software

If you want to play Minecraft, make sure you have the latest version of Java software. Not having the latest version installed may cause certain elements to conflict with Minecraft, thus, causing an error.

So that’s it from us on io.netty.channel.abstractchannel$annotatedconnectexception Minecraft error. This error can be a pain for Minecraft fans who love playing this game.

That’s why today we discussed what does this error means, and we also told you about some other names this error is famous with. We also told you about all the causes of this error and how to fix this.

Few things are as frustrating as running into error codes, especially when you have no idea what the problem might be.

What kind of error is: io.netty.channel.abstractchannel$annotatedconnectexception

Simply put it is a connection error, where the computer you are on is trying to establish a connection to the Minecraft server you have chosen and that connection fails either due to the server you are connecting to somehow not recognizing your request or not getting the signal back through to Minecraft.

What is the solution to this error?

If these didn’t help it is time to try some of the more advanced steps.

To start solving this we need to first figure out which path we need to take, and that depends on who is running the server you are trying to connect to, if it is your own server or someone else’s.

If it’s someone else’s server:

If this is someone else’s server you start by checking if you can connect to other servers. If you can connect to other servers the problem is likely not on your side, but a problem with that particular server. Check with the people that run it to see if there are any technical difficulties.

If the problem is present while connecting to multiple different servers then the problem likely is on your side and it likely has to do with your Firewall permissions. Read the steps below to help fix the issue.

Firewall Permissions

Here’s the steps you take to fix your firewall permissions, which are likely causing the error in Minecraft.

1. Go to your Windows search bar and type “Windows Security” and select it when it pops up.
2. On the page that opens select the “Firewall & Network protection” part.
3. On the next page select the text “Allow an app through firewall”.
4. On the page that opens up select “Change Settings”, as shown in the picture below and click “Yes” on the warning prompt.

1. Now look further down the page where you will now be able to interact with the previously greyed out “Allow another App”.
2. There will be a small pop up window with a button labeled “Browse…”, select this and then navigate to the place where you have Minecraft installed.
3. In the Minecraft folder select the MinecraftLauncher file and click “Open”.
4. We will have to repeat the steps above and this time navigate to where you have your Minecraft Server installed and go to the folder “MinecraftServer” and in it select both Java executable files and open those too.
5. Lastly we will stay on the Change Settings page, but this time scroll down the list of allowed apps and features until we see the entries labeled “Java(TM ) Platform SE binary”. Here we tag all the checkmarks for “Private” at the very least and “Public” too if we run a server and want people to connect from outside our network.
6. Start Minecraft again and check if you now have access to the server.

If it’s your own server:

If this is your server and you cannot connect to it then the first solution is to check if you have started the server before trying to connect to it. Sometimes it’s the simple things!

If your server is running then the solution is most likely going to be one of the following two:

1. Your firewall is blocking your access.
2. You need to portforward your network.

The way to fix problem 1 is the same for both your own server and other people’s servers. We listed the steps you can take above under the header “Firewall Permissions”.

If option 1 didn’t solve your issue then perhaps the issue is option 2: portforwarding your network.

Since this is a problem with your router and every router has a different user interface, it is hard to describe precise steps to take. We will therefor stick to general steps to guide you that should help you fix the problem.

Portforwarding Your Network

Here’s the steps you take to portforward your network to help you fix the Minecraft error.

1. Login to your router. If you have not entered any device name, Username or password for this before, you can likely find them on a sticker on the bottom of your router or in the papers you got with your router.
2. Navigate to the “Port Forwarding” section. This may also be called “Virtual Server”. You might have to look under the “Advanced” options.
3. You should now be on a page where you can enter a Device name, a Port, an IP address and the option to choose a Protocol.
4. Fill in those fields with the appropriate information, by looking up the info on your computer. For the Protocol the option is usually TCP/UDP or Both.
5. Click “Apply” or “Save” to finish.
6. Start Minecraft again and check if you now have access to your server.

Conclusion

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.
