Of the 90 million players, 20% cannot connect to the Minecraft server. Reports indicate that they are unable to connect to the server due to a timeout error.

I went through it too, man! After 9 hours of continuous research, I found the seven easiest steps to fix the Minecraft io.netty bug report.

What does io.netty.channel.abstractchannel$annotatedconnectexception mean?

Minecraft’s io.netty.channel is a connection timeout error that prevents you from connecting to the game server. The main reason for Minecraft’s connection failure is a common IP connection problem.

Error type: Internal exception: java.io.ioexception

Simply put, it is an Internet connection error. Your computer is trying to connect to the Minecraft server of your choice, and that connection will be broken while you are traveling between the server and your computer.

Realm connection speeds may vary depending on players, devices and networks. If connection errors or timeouts occur in the areas, you can take several actions to resolve the problem:

Enable Java Native Sandbox

The native Java sandbox allows you to run Java applications such as Minecraft in a limited environment, which can bypass anything that causes connection problems to the server. You can activate it by following these steps:

• Go to the Windows taskbar search bar, usually at the bottom of the screen, type “control panel” and click on the entry that appears.
• Find the “Programs” section and click on its title.
• The “Java” icon should appear on the next screen. Click on the title. We marked the Java header and the Java symbol in red in the figure below.
• You should now see a small window called “Java Control Panel”. In it, switch to the “Advanced” tab and scroll down until you see a section called “Advanced security settings”. We marked this section in red in the figure above.
• Here it is possible to activate a limited operating system environment (a custom sandbox). Make sure that it is installed, click “Apply” and then click “OK”.
• It is very important to reboot your computer now for the changes to take effect.

After restarting the computer, restart Minecraft and see if you are connected to the server. If not, you can disable your own sandbox again so that you don’t add any more parameters to the problem you want to find.

Reset the modem / router

Rebooting the router is the easiest solution. If your Internet modem / router has problems, you are likely to encounter a Minecraft error. You should always check your Internet connection before trying to connect to the server.

Turn off your router for a few minutes, then turn it back on to restart the router. If this does not work, reset all settings on the router and configure it again. After restarting the router, try to connect to the server.

Domain services are automatically installed at the physical location nearest the IP address of the domain owner. For example, if you live in the U.S., but the zone to which you connect is in Australia, the connection speed may be slightly lower than that of the zone owner.

If you have another technical problem with your domain, please contact customer support, briefly describe the problem, specify the domain name and your Xbox Live player tag.
