  1. Bad internet connection.

Another reason could be your internet connection. It is preventing your PC from connecting to the online server. Slow connection speed obfuscates the information between the server and the host PC. There is a chance that the link will time out. It shows that your computer’s data transfer is very slow. The server considers the connection to time out. It does not receive the necessary information immediately.

You can verify your Internet connection once again. Online websites can help you determine the bandwidth speed of your connection. There are many websites available on the internet. Upload and download speeds can be measured on these websites. This will inform you if the problem is with your internet connection.

  1. Server is Overburden

The number of players on the game server you are trying to connect to may be too high for this. All of them are trying to contact the gaming server. You only have a few options for exercise, and it’s best to wait. You can try to connect to the server later when the load on their server is (somewhat) less.

Solutions To Fix io netty channel abstract channel annotated connect exception

  • Reset Internet Connection

The most basic way is to reset the router. If your internet modem/router is faulty, then Minecraft server errors are most likely to occur. Before attempting to connect to a server, you should always check your Internet connection.

  1. To restart your router, try turning it off for a few minutes.
  2. Reconnect the power cable after 3-5 minutes have elapsed.
  3. Then turn it back on. If that doesn’t work, reset your router’s settings and set it up from scratch. After rebooting the router, try connecting to the server.
  • Check for Port Forwarding / Filtering

Connect to your router and log in. This is the first time you have submitted a device name, username or password. You’ll probably find them on the sticker on the bottom of your router or in the instructions that come with it.

Navigate to the “Port Forwarding” section of the menu. It is also known as a “virtual server“. You may have to search in the “Advanced” section.
You will be directed to a screen where you can type in the device name, port and IP address. There is also the opportunity to select a protocol.

  1. Viewing the information on your computer, fill in those fields with the correct information. TCP/UDP or both are usually options for the protocol.
  2. To finish, click “Apply” or “Save“.
  3. Restart Minecraft and see if you can connect to your server now.
  • Update Java Software

Minecraft requires the latest version of Java to function correctly. You are trying to connect to the server using an older java file version. Minecraft will struggle with missing elements. You will land on java.net. ConnectException The connection did not provide any further information.

More specifically, java.net.connectexception The connection timed out. No further information problem found on Windows 10. If you get the Java.net Connectexception Minecraft issue, you don’t have a Learn to Mod account. This can be resolved by updating the Java program to the latest available version.

  • Add Exceptions to Firewall for Minecraft Server

The Windows Firewall you are working on is conflicting with your server connection. Some executables in the Minecraft folder require an internet connection. You need to discount the firewall.

  1. To enter the Settings menu, go to the Start menu and select the Settings icon.
  2. Select “Update & Security” from the given settings menu.
  3. Select the “Firewall and Network Security” option under “Windows Security” in the left-hand panel.
  1. Select the “Allow an app through firewall” option from the menu.
  2. On the warning message, click “Change Settings” and select “Yes.”
  3. Select the “Allow any other app” option from the menu and then select “Browse.”
  4. Select the Minecraft game and launcher executable from the Minecraft install directory folder.
  5. Repeat the previous steps, but this course leads to the directory where the Minecraft servers are stored.
  6. Now, open the “MinecraftServer” and “Maxwell” folders.
  7. Inside let both java executables run in the same way.
  8. Now go through the process one more time. After selecting the “Change” option, instead of clicking “Allow another app“, click “Allow another app“. Just browse through the list of apps to find what you’re looking for. Allow all “Java Platform SE binary” options to be used on both private and public networks.
  • Reset Network Configuration (Command Prompt)

It is also possible that your Windows network setup is to blame. Your network settings may be wrong. This can cause an interruption between the host server and the game server. Follow the methods here to reset the network configuration.

  1. Go to the Windows Search bar (bottom left) and type “command prompt” and then press “Run as administrator“.
  2. Once opened, type the following command in the Command Prompt window.
  3. Check if the problem persists even after restarting your computer.
  • Add IP Address and Port

You cannot have a static IP address. This will change every few days or reset your internet connection. We will verify the IP address and exact port for the game. Also, we need to add it to Minecraft Launcher at this stage.

  1. Type “command prompt” in the Search window on the Windows toolbar.
  2. Prefer “Run as administrator” option from the menu after right-clicking on the icon.
  3. Type “ipconfig” and press Enter. Note the “IPv4 address”.
  4. Now, you need to initialize the “Server Properties” text document present in “Minecraft Servers”. Go to the folder, then Maxwell (XYZ), and then to the “MinecraftServer” folder.
  5. Note the entry “Server Port” (say 12345).
  6. Now launch Minecraft Game and go to the “Play Multiplayer” menu.
  7. Simply click on the server you need to join. You can choose “Edit” from the options below.
  8. Right-click on the server and select “Edit”.
  9. The server name can be whatever you like. The “address” must be the IPV4 address. For example, “XXX.XXX.X.X:12345,” where the port number differs from “12345.”
  10. Click “Done” and then “Refresh” to check if the problem still exists.
  • Check ISP Network Access for Minecraft Servers

If none of the preceding methods work, you should have network access checked by your ISP. ISPs will rarely block network routing for specific domains. It blocks you from accessing a specific server. Check with your ISP to see if Internet routing is really restricted.

You can also switch your internet connection to 3G on your smartphone and see how it works for you. If it does, your ISP is probably blocking you, and you’ll need to switch networks.
