Uninstall incompatible Software or Program to Minecraft

There are incompatible software or programs installed in your system you can’t access the Minecraft server, or they make it hard through various errors like io.netty.channel.abstractchannel$annotatedconnectexception.

Well, now how would you know which programs or software you have which are not compatible with Minecraft?

There is a list of such programs you can search online, and read about them. If you have any of them installed, uninstall them right away to enjoy a smooth sailing of Minecraft game.

Programs such as Virtual Ethernet, Hamachi, and many others produce a conflict with Minecraft and make it hard for the code to run smoothly.

Plus, install only genuine and authenticated plugins or software in your system, if you have malicious software or programs installed, then you may face a conflict error.

Well, if you are certain that you don’t have a Virtual Ethernet Connection with Hamachi installed on your PC, that’s Okay.

If not, then try to check it in the control panel, and see if you have any program or software with the name installed.

Check your IP address and Port

Static IP is one of the finest things you can get to enjoy a seamless Minecraft gaming address. With a static address, connecting to the internet won’t change your IP address.

If you don’t have a static IP address, when you connect to the internet, every time it changes your IP address which is making it hard for you to connect without getting an error.

Press WINDOWS+R a new window will appear, type CMD and you will enter the command prompt. Now type IPCONFIG and take note of the IPV4 address.

Go to Minecraft server Folder -> Maxwell -> MinecraftServer. Open the server properties text document and check the number under the server Port.

Now launch Minecraft and go to the Multiplayer option

Select the chosen server and click on Edit. The IPV4 server and server port we have found and noted, enter there and click done.

Restart your PC, and you will see the issue does not persist now.

Portfowarding Network100

Portforwarding network100 too is an effective way to eradicate this problem and fix connectivity server errors.

To get this done follow me along.

Access your WI-FI router settings by entering the name and password.
Click on the Portforwarding tab then Virtual server and then Advanced.
Note down your device name, port, and IP address. Keep In mind, save these things somewhere you could instantly access because we are going to use this information.
Fill this info in your computer settings and save.
Choose the protocol, don’t worry, it won’t be a big difference if you pick TCP or UDP or both.
Apply and save the settings.

Restart your Minecraft, try to see if the issue persists, and hope it will be fixed.

Slow internet or multiple users from the same server trying to access the same gaming server

That happens, especially in college hostels and others where gamers gather under one roof.

There is no solution for that, what you can do is wait, and check if there is a load released on the server to help you connect again.

But most of the time, it’s because of your poor internet connection. If you have a poor internet connection, which surely will stop you from getting the online server.

A slow internet connection takes time to convey the info between your server and the gaming server which leads to a time-out error.

Check your internet connection bandwidth speed, and verify if it is good for playing Minecraft games.

If not then, go with another service provider, and let the incumbent network provider go away.
