Most Minecraft players who encounter the “io.netty.channel.ConnectTimeoutException connection timed out” error try to connect to a co-op game over the local network or the Internet.

Before proceeding, we also recommend trying an automatic repair solution like ReimageMac Washing Machine X9 to hopefully fix the “io.netty.channel.ConnectTimeoutException connection timed out” error quickly.

Solution 1. allow Minecraft in the firewall

Incorrect settings in the firewall can block the connection to Minecraft servers. Therefore, the first thing to do is to make sure that the connections are allowed:

  • In the Windows search, type Control Panel and press the Enter key
  • Go to the section System and Security
  • Select under Windows Defender Firewall select the option Allow apps to communicate through Windows Firewall
  • Click on Change settings
  • Scroll down until you see all entries of Java (TM) Platform SE Binary and select the checkboxes there Private and Public
  • Click on OK and close the Control Panel

Solution 2. disable antivirus program and VPN

Connection errors such as “io.netty.channel.ConnectTimeoutException connection timed out” can occasionally also be caused by applications that intercept (or completely prevent) the Internet connection. If you have a standalone AntiVirus installed, meaning it is not built into Windows (also known as third-party software), you should temporarily disable the program and see if that solves the problem. Most security applications cannot be disabled, so uninstalling them may be necessary:

  • In Windows search, type Control Panel and press the Enter key
  • Navigate to Programs > Uninstall a program
  • Locate your antivirus program, right-click on it and click right mouse button and select Uninstall
  • Follow the instructions on the screen and then restart the computer

If you are still using a VPN for this, disable it as well before trying to connect to the Minecraft servers, as this could also be a cause of the error message.

Solution 3. reset the router

The ISP provides users with a dynamic IP address by default, which means that the IP address changes every time the Internet connection is restarted (you can also use a static IP address, which can also help fix the “io.netty.channel.ConnectTimeoutException connection timed out” error in some cases – you will need to contact your ISP for this). To get a new IP address assigned, you just need to reset your router:

  • DO NOT press the reset button on your router to reset it, as this may reset it to factory defaults
  • Instead, simply unplug the plug from the power outlet or unplug the cable from the device
  • Wait at least 30 secondsbefore restarting the router

Solution 4: Set the correct port and IPv4 address

  • Type cmd in the Windows search
  • Click with the right mouse button on the search result and select Run as administrator
  • In the new window, type the following command and press Enter:
