The Common IP Connectivity issue is the culprit of the issue. The issue can occur on both single player and multiplayer servers. Here are easy steps to fix it.
Fix 1: Add exceptions to Firewall settings in Minecraft folder
The best method to fix the io.netty.channel.connectimeoutexception connection timed out is adding exceptions in Firewall settings. In some cases, you are blocked by the VP and Windows Firewall from accessing to the server of Minecraft game. To fix everything, you will have to add some exceptions in Firewall in order to avoid the abstractchannel annotatedconnecexception connection refused error. Here are the steps to follow to add the exceptions to Firewall settings:

- The ninth step is to repeat the process and allow the Java executables that can be found inside the folder.
- Then, repeat the fourth step and simply scroll down to the list of the Java Platform SE Binary instead of Allow another app.
- Finally, allow all the Java Platform SE Binary options by both Private and Public networks.
Fix 2: Delete the unstable software
Some unstable software can cause conflict when you install it on your computer. The list of the software that are not compatible with the Minecraft game are available in many websites. The only ones that should be removed are the false plugins and add 100% authenticated plugins only.
The Virtual Ethernet with Hamachi is one of the incompatible software. It is better for you to either disable or delete the software.
- At the beginning, you will have to open Command Prompt and enter “ipconfig”.
- Then, locate the configuration called Virtual Ethernet Connection with Hamachi.
- Once you find it, write down the addresses and go to the search panel to delete the Virtual Ethernet software with Hamachi.
- Afterward, enter your IP and port number to the server and fix the issue. For anyone who is planning to play with your friends, setting up a Hamachi server is also allowed.
Fix 3: Add IP address and choose the working port that suits well
The issues related to the refusing of connection in Minecraft will happen if the IP address and port that you are using is dynamic in nature. The way out is to change your IP address and add it to the Minecraft Launcher. Here is the guide to add the IP address and choose the suitable working port:
- Firstly, run the Command Prompt as Administrator.
- The second step is to enter the command “config” and write down the IPV4 address.
- Next, browse to the Minecraft Servers folder > Maxwell > Minecraft Server at one and open Server Properties text document.
- Do not forget to write down the Server Port and open up the game and go to the Play Multiplayer option.
- Choose the server, the one that you want to join, and then choose Edit.
- After that, you will have to enter the IPV4 address and click Done. In the end, you can connect to a server using the IPV4 address.
- When everything is done, refresh to apply changes.
Fix 4: Reset the modem or router
Resetting the router is the faster way. You are most likely to notice the Minecraft error if there is something with your internet modem or router. Before trying to connect to the server, you are suggested to always check your internet connection.
If you want to try this method, you can try to power off your router for a few minutes and power back to restart your router. If it is not that helpful then reset all the settings of your router and set it up freshly. After setting the router, you can try to connect to the server.
Fix 5: Use a trusted VPN connection source
Minecraft might be banned in your region. The Minecraft servers are sometimes blocked by the Windows Firewall, which is why you cannot connect to the server. The same thing goes for VPN. Changing servers frequently can lead the Host server being blocked. In this case, you can try to use the trusted VPN apps that do not block your Minecraft game server. All that should be done is to simply change the region that may be useful to overcome io.netty.channel.connectimeoutexception.
Fix 6: Update Java software
If you want Minecraft to work properly, you will have to get the latest version of Java. For those who are attempting to connect to the server with an outdated Java software, the missing elements will cause the conflict with the game, which is the reason why the io.netty.channel.connectimeoutexception is seen. Usually, the Java.net.connectexception connection timed out no further information error is seen on Windows 10. The thing called Learn to Mod account is important to join a server of Minecraft. The Java.net.connectexception Minecraft error means there is no need for you to have any Learn to Mod account. You can fix it by updating the Java software to its current version. In addition, you can also allocate more RAM to Minecraft for fast and upgraded gameplay.
