Everyone who loves to play games has likely come across different kinds of issues that affect their fun time. This is especially true to multiplayer games like Minecraft.
Minecraft is an awesome game with advanced features, such as cross-platform multiplayer play. Although it is played and loved by many, this ambitious game is not a stranger to bugs and issues that prevent players from having a fun and enjoyable experience. One of the many issues that Minecraft players face is the Minecraft io.netty.channel.ConnectTimeoutException connection timed out error.
What is this error code all about? Let’s dive right it.
About the io.netty.channel.ConnectTimeoutException Connection Timed Out Minecraft Error
Released in 2011 by Mojang Studios, Minecraft is a video game that was soon acquired by Microsoft. Since then, it has become very popular with more and more players joining the community. As of this year, the game already has 126 million users, which is indeed an impressive number. Unfortunately, as with most games, it may throw unexpected issues that can ruin a player’s fun time. One is the io.netty.channel.ConnectTimeoutException connection timed out error.
According to players, the error shows while trying to connect to a co-op game through a local network or via the internet. Sometimes, it occurs when trying to connect to a server. But what causes it to show?
What Causes the io.netty.channel.ConnectTimeoutException Error?
After investigating this error code, it turns out that it is caused by various culprits. These include:
- Port Number Mismatch – It is possible that you are seeing this error because your port number does not match the port number of the game’s server. If this is the case, you can resolve the issue by checking your port and editing it on the game’s settings.
- Inconsistent DNS Settings – DNS inconsistency can cause this error message, too. To resolve the problem, you have to switch and use the DNS values given by Google.
- IP Inconsistency – One of the most common culprits behind this error is IP inconsistency. To fix this, simply reboot your router.
- JRE Blocked by Antivirus – Third-party antivirus programs can cause the connection timed out error message to surface. Simply disable or uninstall the program to eliminate the problem.
Because the error prevents users from accessing the game, it has quickly become a major issue that players want to immediately fix. Many players have turned to online forums and sites like Reddit to express their frustrations and seek help.
Though the error message hints that the game was not able to establish a connection to the server, it does not give out more information. The first workaround they tried is to check any internet issues. But does it really work?
Ways to Resolve the io.netty.channel.ConnectTimeoutException Connection Timed Out Minecraft Error
In this section, we will share with you some solutions you can try to hopefully get rid of the connection timed out error.
Solution #1: Adjust your firewall settings
If your firewall’s settings are not properly set, it could block any connections to Minecraft’s servers. To prevent this from happening, make sure that any attempt to connect to the game’s servers goes through without problems.
Here’s what you should do:
- Into the Windows search field, input control panel and hit Enter.
- Go to the System and Security section.

Solution #2: Disable your VPN and antivirus program
Apps that affect your internet connection can sometimes trigger the io.netty.channel.ConnectTimeoutException connection timed out error message. These apps include your VPN and antivirus programs.
